Practical Applications of Quantum Computing: Coming to a Screen Near You

Practical Applications of Quantum Computing: Coming to a Screen Near You

Meta Description: HSBC just used it to beat Wall Street at bond pricing — and your bank, phone, and doctor’s office may be next. Here is how quantum goes mainstream in 2025.

Introduction

“We spent all day chasing 2% improvements. This gave us 34% — in one shot.”

That is Josh Freeland, HSBC’s global head of algo credit trading, describing the moment his team realized quantum computing had just rewritten the rules of finance.

In September 2025, HSBC and IBM made history: using real European bond trading data and IBM’s Heron quantum processor, they boosted bond price prediction accuracy by 34% — the first time a bank has demonstrated quantum advantage on production-scale financial data (Bloomberg; Reuters).

Quantum computing is not a a lab curiosity anymore. This is a Sputnik moment — the spark that ignites a race across banking, healthcare, logistics, and AI.

If you think quantum computing is still decades away, you are already behind.

In this post, you will discover:

  • How HSBC’s breakthrough actually works — and why 34% changes everything 
  • The 5 industries where quantum computing is going live right now (not in 2040)
  • Real products and services already using quantum — from fraud detection to drug discovery
  • Why your next smartphone might tap into a quantum cloud
  • The hidden bottleneck: error correction, talent gaps, and the “quantum winter” risk
  • What to watch in 2025–2027 — and how to prepare your business

Quantum is already here. And it is about to touch your screen, your wallet, and your life.



The HSBC Breakthrough: Quantum’s First Real-World Win in Finance

For years, quantum computing lived in headlines like “Google achieves quantum supremacy!” — solving abstract problems with no practical use.

HSBC changed that.

What They Did:

  • Data: Anonymized, real-world European over-the-counter (OTC) bond trades — messy, noisy, and complex.
  • Hardware: IBM’s Heron processor — the most advanced in IBM’s quantum fleet as of 2025 (IBM roadmap).
  • Algorithm: A hybrid quantum-classical model that used quantum circuits to simulate market microstructure and price elasticity.
  • Result: 34% improvement in predicting whether a bond would trade at a given price — a large edge in a market where 1% = millions (Financial News London).
“This was not a toy problem. It was production-scale, with real data, real constraints, and real economic impact.” — Philip Intallura, Group Head of Quantum Technologies, HSBC

Why This Matters:

In bond markets, liquidity is king. Mispricing a trade by even 0.5% can mean losing a client or taking a loss. HSBC’s quantum model does not just predict — it optimizes execution strategy in real time, reducing slippage and improving capital efficiency.

And they did not do it alone. A 16-person team of quantum physicists, ML engineers, and traders worked “around the clock” to validate the results — proving quantum can integrate into live financial workflows.

“If you could get this result every day, that would be quite something.” — Josh Freeland, HSBC

5 Industries Where Quantum Is Already Live

1. Banking & Trading: The New Arms Race

HSBC is not alone. Wall Street is all-in:

  • JPMorgan Chase: Generated truly random numbers on Quantinuum’s quantum computer — certified via a Nature paper — which supports secure cryptography and fair trading (Nature; JPMorgan release).
  • Goldman Sachs: Testing quantum Monte Carlo simulations to price complex derivatives 1,000x faster.
  • Citigroup: Partnering with Microsoft Azure Quantum to build fraud detection models that spot anomalous transactions in milliseconds.
“When one bank gets it, the others will not sleep until they have it too.” — Miklos Dietz, McKinsey Senior Partner

McKinsey estimates quantum could unlock $72 billion in annual revenue by 2035, with finance capturing 25% of that (McKinsey Quantum Monitor 2025).

2. Drug Discovery: Simulating Molecules, Not Guessing

Classical computers struggle to model complex molecular interactions.

Enter quantum:

  • Roche & Cambridge Quantum: Simulated serotonin receptor binding to speed antidepressant development.
  • Boehringer Ingelheim: Used Google’s Willow processor to model enzyme reactions for diabetes drugs — cutting R&D time from 5 years to 18 months.
  • Startups like Zapata AI: Offer “quantum-as-a-service” for biotech via cloud platforms.

Result? Drugs designed in silico with quantum precision — fewer failed trials, faster cures.

3. Logistics & Supply Chains: Solving the Unsolvable

The traveling-salesman-type problems scale fast. At 100 stops, classical supercomputers choke.

Quantum optimization helps:

  • Volkswagen: Used D-Wave annealers to optimize traffic flow for 10,000 taxis in Beijing — reducing congestion by 22%.
  • Maersk: Testing quantum routing for global container ships, saving $200M/year in fuel and delays.
  • UPS & FedEx: Piloting quantum-powered last-mile delivery in 2025 trials.

4. AI & Machine Learning: Quantum-Enhanced Intelligence

Quantum does not replace AI — it supercharges it.

  • Quantum kernels: Speed up support vector machines for fraud detection (used by HSBC and Mastercard).
  • Quantum neural networks: Process high-dimensional data (such as medical imaging) with fewer parameters.
  • TensorFlow Quantum: Lets developers build hybrid models that run on classical + quantum hardware.

Your recommendations or credit score may soon use quantum co-processors in the cloud.

5. Cybersecurity: The Double-Edged Sword

Quantum breaks older encryption (RSA, ECC) — but also enables stronger protections.

  • Quantum Key Distribution (QKD): Already deployed by banks in Switzerland and China via fiber networks.
  • Post-Quantum Cryptography (PQC): NIST finalized core algorithms in 2024, with more progress in 2025; platform vendors are rolling them into systems by 2026 (NIST FIPS; NIST PQC project).
  • HSBC & JPMorgan: Using quantum random number generators to secure high-frequency trading.

How Quantum Computing Actually Works (Without the Physics Degree)

Forget “qubits are 0 and 1 at once.” Here is what matters for practical use.

The Hybrid Model: Quantum + Classical = Real Results

Today’s quantum computers are noisy (NISQ era). They cannot run full algorithms alone.

So teams use hybrid workflows:

  1. Classical pre-processing: Clean data, reduce dimensionality.
  2. Quantum acceleration: Offload the hardest math (optimization, simulation) to the quantum chip.
  3. Classical post-processing: Interpret results and integrate into business logic.

HSBC’s bond model used this pipeline — and it worked (Reuters coverage).

Hardware Leaders in 2025:

Company Processor Qubits Key Strength
IBM Heron ~133–156 Lower error rates; modular architecture (IBM)
Google Willow ~70 Supremacy-class experiments and chemistry work
Quantinuum H2 ~32–56 High fidelity (trapped ions); certified randomness (Nature)
Rigetti Ankaa-2 ~84 Accessible via public clouds

You do not need your own quantum computer. Quantum cloud (IBM Quantum, AWS Braket, Azure Quantum) lets anyone run experiments today.

The Roadblocks: Why Quantum Is Not in Your Phone (Yet)

Error Correction: The Biggest Hurdle

Qubits are fragile. Heat, vibration, even cosmic rays cause decoherence. Current error rates require thousands of physical qubits to make one stable “logical qubit.” IBM’s roadmap targets much larger systems by the late-2020s (IBM).

Talent Gap: Fewer Than 5,000 Quantum Developers Worldwide

Universities are launching programs, but demand exceeds supply. Companies are hiring physicists, ML engineers, and domain experts.

Cost vs. ROI: “Quantum Winter” Fears

If practical wins stall, funding could slow. HSBC’s result shows economic value, not just technical promise (McKinsey).

What Is Next? 5 Quantum Milestones to Watch (2025–2027)

  1. Quantum Advantage in Portfolio Optimization (Goldman Sachs, 2026): Beating classical solvers on real client portfolios.
  2. FDA-Approved Quantum-Designed Drug (Roche or Merck, 2027): First medicine born from quantum simulation.
  3. Quantum Co-Processors in Data Centers (Microsoft + Azure, 2026): Hybrid chips accelerating AI workloads.
  4. National Quantum Internet Testbeds (US, EU, China): Secure communication via entangled photons.
  5. Consumer Quantum Apps: Banking apps use quantum to detect fraud; health apps simulate metabolism.

How to Prepare: A Practical Guide for Businesses & Developers

For Enterprises:

  • Audit high-value problems: Where do you hit computational walls? (risk modeling, logistics, R&D)
  • Partner early: Join IBM Quantum Network, AWS Braket Partners, or Microsoft’s programs.
  • Upskill teams: Train data scientists in Qiskit or Cirq.

For Developers:

  • Learn Qiskit or PennyLane: Open-source frameworks with cloud access.
  • Build hybrid models: Start with quantum-inspired classical algorithms.
  • Contribute to open-source: Qiskit Nature (chemistry) or Qiskit Finance.

For Everyone:

  • Adopt quantum-safe encryption: Ask providers about PQC readiness (NIST FIPS).
  • Watch for “quantum-washing”: Look for peer-reviewed results or production data (Nature article).

The Basics of Quantum Mechanics Simply Explained

The Basics of Quantum Mechanics Simply Explained

Quantum mechanics is a captivating yet perplexing branch of physics that unveils the mysterious behavior of matter and energy at the tiniest scales—those of atoms and subatomic particles. Unlike classical physics, which governs the predictable motion of everyday objects like cars or planets, quantum mechanics introduces a realm where rules defy intuition, and probabilities reign supreme. Particles can exist in multiple states simultaneously, and observing them alters their behavior in ways that challenge our understanding of reality. This field isn’t just an academic curiosity; it’s the foundation of modern technologies like transistors, lasers, and MRI machines, which have transformed our world.

The story of quantum mechanics began over a century ago, sparked by a crisis in classical physics known as the ultraviolet catastrophe. In 1900, Max Planck proposed that energy is emitted in discrete packets, or quanta, a radical idea that laid the groundwork for quantum theory. Albert Einstein built on this in 1905, explaining the photoelectric effect—where light ejects electrons from a metal surface—by treating light as both waves and particles (Einstein, 1905). Niels Bohr then revolutionized atomic models in 1913, suggesting electrons occupy quantized orbits. These pioneers, along with later giants like Erwin Schrödinger and Werner Heisenberg, shaped a theory that’s now essential to science and technology. Today, quantum mechanics fuels cutting-edge fields like quantum computing, promising to solve problems beyond classical computers’ reach.

In this guide, we will demystify the core concepts of quantum mechanics, explaining them in simple terms with relatable examples and analogies. From the dual nature of particles to the spooky connections between them, we’ll cover the essentials without drowning you in jargon. Along the way, we’ll weave in historical context, real-world applications, and insights from experiments, supported by data and references to authoritative sources. Whether you’re a beginner or brushing up on the basics, this post will equip you with a solid grasp of quantum mechanics and its profound implications.

Wave-Particle Duality

One of the most astonishing revelations of quantum mechanics is wave-particle duality, the idea that particles like electrons and photons can behave as both waves and particles, depending on how we observe them. This defies classical logic, where objects are distinctly one or the other—think of a ball versus a ripple in a pond. In the quantum world, this distinction blurs, revealing a deeper truth about nature.

The double-slit experiment is the poster child for this phenomenon. Picture a setup where electrons are fired at a barrier with two narrow slits, behind which lies a screen. When both slits are open and no one watches which slit the electrons pass through, they create an interference pattern—alternating bands of light and dark—typical of waves overlapping and either amplifying or canceling each other. Astonishingly, this pattern emerges even if electrons are sent one at a time, suggesting each electron somehow passes through both slits and interferes with itself. Yet, if we place a detector at one slit to peek at the electron’s path, the interference vanishes, and we see two simple bands, as if the electrons reverted to particle-like behavior (Young, 1804; Davisson & Germer, 1927).

 

[Insert image here: Illustration of the double-slit experiment demonstrating wave-particle duality. Alt text: "Illustration of the double-slit experiment demonstrating wave-particle duality."]

This experiment, first conducted with light by Thomas Young in 1801 and later with electrons by Clinton Davisson and Lester Germer in 1927, underscores a key quantum idea: the wave function. Represented mathematically as ψ (psi), the wave function encodes a particle’s probability of being found in a given state. Its square, |ψ|^2, predicts where the particle is likely to appear. In the double-slit setup, the wave function splits, passes through both slits, and interferes, shaping the pattern on the screen. Observing the electron collapses this wave function into a definite state, a process tied to the act of measurement.

Wave-particle duality isn’t limited to electrons. Photons, neutrons, and even molecules like buckminsterfullerene (C60)—with 60 carbon atoms—have shown similar behavior in experiments (Arndt et al., 1999). A 1999 study at the University of Vienna fired C60 molecules through a diffraction grating, observing an interference pattern, proving that even relatively large objects obey quantum rules. This universality hints at why quantum mechanics underpins everything from atomic structure to the behavior of stars. For a hands-on exploration, check out the University of Colorado’s interactive simulation (PhET, 2023).

Superposition

Superposition takes quantum weirdness up a notch, asserting that a quantum system can exist in multiple states at once—until it’s measured. Imagine flipping a coin that’s simultaneously heads and tails while in the air, only settling when it lands. In quantum mechanics, particles like electrons can be in a blend of states—say, spinning up and down—until an observation forces them into one outcome.

The famous Schrödinger’s cat thought experiment illustrates this vividly. Picture a cat in a sealed box with a radioactive atom, a Geiger counter, and a vial of poison. If the atom decays, the counter triggers the poison, killing the cat. Quantumly, the atom is in a superposition of decayed and not decayed until observed, meaning the cat is both alive and dead until we look. Proposed by Erwin Schrödinger in 1935, this isn’t a real experiment but a way to highlight superposition’s strangeness at larger scales. In practice, macroscopic objects like cats lose superposition due to decoherence—interactions with the environment collapse the quantum state—but the principle holds for tiny systems (Schrödinger, 1935).

[Insert image here: Diagram showing the concept of superposition in quantum mechanics. Alt text: "Diagram showing the concept of superposition in quantum mechanics."]

Superposition shines in real experiments, like the Stern-Gerlach setup from 1922. Here, silver atoms pass through a magnetic field that splits them into two beams based on spin—up or down. Before measurement, each atom is in a superposition of both spins, only choosing a state upon detection. Modern tests push this further: a 2021 study in Nature put a sapphire crystal with 10^16 atoms into a superposition of vibrational states, hinting that quantum effects might scale up more than we thought (Marletto et al., 2021). This property is the backbone of quantum computing, where qubits—unlike classical bits fixed at 0 or 1—can be 0, 1, or both, enabling massive parallel processing.

For more, the Quantum Institute’s guide offers a clear breakdown (Quantum Institute, 2021). Superposition isn’t just theoretical—it’s a practical tool driving tomorrow’s tech innovations.

Entanglement

Entanglement is often dubbed “spooky action at a distance” by Albert Einstein, who co-authored the 1935 EPR paradox paper questioning it (Einstein et al., 1935). It occurs when two or more particles become linked, so the state of one instantly affects the other, no matter how far apart they are. Measure one particle’s spin, and the other’s spin is instantly set, even across galaxies.

The EPR paradox argued this implied quantum mechanics was incomplete, suggesting hidden variables predetermined the outcomes. But John Bell’s 1964 theorem and subsequent experiments, like Alain Aspect’s in 1982, disproved this. Aspect’s team entangled photons and measured their polarizations 12 meters apart, finding correlations too strong for classical explanations—confirming entanglement’s reality with a statistical significance exceeding 99% (Aspect et al., 1982). A 2015 experiment in the Netherlands pushed this to 1.3 kilometers, closing loopholes and reinforcing quantum theory’s predictions.

Entanglement powers quantum teleportation, where a particle’s state is transferred to another without moving it physically. In 2017, Chinese scientists teleported a photon’s state from Earth to a satellite 1,400 kilometers away, a feat unimaginable without entanglement (Ren et al., 2017). It’s also key to quantum cryptography: the BB84 protocol uses entangled particles to detect eavesdroppers, as any interference disrupts the system, ensuring secure communication.

This phenomenon isn’t just lab trickery—it’s reshaping technology. Dive deeper with the Institute for Quantum Computing’s tutorial (IQC, 2020).

Heisenberg’s Uncertainty Principle

Werner Heisenberg’s uncertainty principle, introduced in 1927, states that you can’t precisely know both a particle’s position and momentum at the same time. The more you pin down one, the fuzzier the other gets. Mathematically, it’s Δx · Δp ≥ ħ/2, where Δx is position uncertainty, Δp is momentum uncertainty, and ħ is the reduced Planck’s constant (Heisenberg, 1927). This isn’t about imperfect tools—it’s a fundamental limit baked into nature.

Think of trying to photograph a speeding car with a fast shutter: you’ll catch its position sharply but blur its motion. A slower shutter captures motion but smears the position. In quantum terms, a particle’s wave function spreads out when its position is vague, tightening its momentum range, and vice versa. This explains why electrons don’t crash into atomic nuclei: confining them too closely spikes their momentum, boosting kinetic energy and keeping them in orbit.

Experiments bear this out. A 2012 study at the University of Toronto measured photons’ positions and momenta, confirming the uncertainty relation with high precision (Rozema et al., 2012). In atoms, it sets the ground state energy: the hydrogen atom’s electron has a minimum energy of -13.6 eV, a direct result of balancing position and momentum uncertainties. For a detailed look, see MIT’s lecture notes (MIT, 2018).

Quantum Tunneling

Quantum tunneling lets particles slip through barriers they shouldn’t classically cross. Imagine rolling a ball up a hill—it stops unless it has enough energy to reach the top. In quantum mechanics, a particle’s wave function extends beyond such barriers, giving it a chance to appear on the other side without “climbing over.”

This powers alpha decay in radioactive nuclei. An alpha particle, trapped by the strong nuclear force, tunnels through the Coulomb barrier—a feat classical physics can’t explain. In uranium-238, this process has a half-life of 4.5 billion years, aligning with quantum predictions. Tunneling also drives the scanning tunneling microscope (STM), which images atoms by measuring electrons tunneling between a tip and a surface. Since its invention in 1981, STMs have mapped materials with angstrom-level precision (Binnig & Rohrer, 1982).

In tech, tunneling underpins tunnel diodes and flash memory, where electrons zip through thin insulators. A 2020 study estimated that tunneling boosts enzyme reaction rates in biology by up to 100 times, hinting at its role in life itself (Klinman & Kohen, 2020). Explore this with the Science Channel’s video (Science Channel, 2022).

Quantum Computing

Quantum computing harnesses superposition, entanglement, and interference to tackle problems classical computers struggle with. Qubits, unlike bits, can be 0, 1, or both, thanks to superposition. Entangle them, and a system of n qubits represents 2^n states at once. A 50-qubit machine could theoretically handle 2^50—or over a quadrillion—combinations simultaneously.

Shor’s algorithm, devised in 1994, could factor a 2048-bit number in hours, a task taking classical supercomputers millennia, threatening RSA encryption (Shor, 1994). Google’s 2019 “quantum supremacy” claim saw its Sycamore processor solve a problem in 200 seconds that a classical machine would take 10,000 years for—though IBM contested this. By 2023, IBM’s 127-qubit Eagle processor marked progress, but decoherence and error rates remain hurdles.

Future applications include simulating molecules for drug discovery or optimizing logistics. Quantum Tech News’ blog tracks these advances (QTN, 2023).

Conclusion

Quantum mechanics unveils a universe where particles dance between wave and particle forms, exist in multiple states, connect across vast distances, defy precise measurement, tunnel through walls, and promise computational leaps. It’s a field born from necessity—solving puzzles classical physics couldn’t—and now drives innovations from semiconductors to quantum networks. Over 30 Nobel Prizes in Physics since 1901 tie to quantum discoveries, a testament to its impact.

This journey through its basics—wave-particle duality, superposition, entanglement, uncertainty, tunneling, and computing—shows a world both strange and beautiful. Dive deeper with the resources below, and let curiosity guide you into the quantum frontier.

Key Takeaways

  • Quantum mechanics governs matter and energy at atomic scales, using probabilities over certainties.
  • Particles exhibit wave-particle duality, acting as both depending on observation.
  • Superposition lets systems occupy multiple states until measured.
  • Entanglement links particles, so one’s state instantly sets the other’s.
  • The uncertainty principle caps how well we can know position and momentum together.
  • Quantum tunneling allows particles to cross impossible barriers, enabling tech and nature.
  • Quantum computing leverages these oddities for unparalleled processing power.

Another Day, Another Quantum Computing Breakthrough (This Time from China)

Another Day, Another Quantum Computing Breakthrough (This Time from China)

In a groundbreaking development that is shaking up the global landscape of quantum computing, Chinese scientists have unveiled a superconducting quantum computer prototype known as “Zuchongzhi 3.0.” This remarkable achievement, marked by 105 readable qubits and 182 couplers, represents not only a leap in performance but also establishes China as a serious contender in the quantum race. The new quantum computer can solve a specific kind of problem (called random circuit sampling) incredibly fast. It can finish these tasks in a fraction of the time compared to even the best traditional supercomputers—specifically, it’s up to a quadrillion (that’s 1 followed by 15 zeros) times faster than them, and about a million times faster than the speeds reported in recent tests by Google. Essentially, this shows that for certain problems, quantum computers have a huge speed advantage over classic ones.

This blog post explores the significance of this advancement, the technology behind it, and its implications for the future of quantum computing on a global scale.


Understanding Quantum Computational Advantage

Quantum computational advantage, often termed “quantum supremacy,” refers to the point at which a quantum computer can solve a specific problem faster than the best available classical computer. In the case of Zuchongzhi 3.0, the device has been engineered to perform tasks—such as quantum random circuit sampling—with unprecedented speed. This milestone is not just a demonstration of enhanced hardware capabilities; it serves as a direct measure of the scientific and technological prowess behind the research. By performing a task that would take classical supercomputers billions of years to simulate, Zuchongzhi 3.0 provides tangible evidence of the potential for quantum machines to revolutionize computing in fields as diverse as cryptography, materials science, and artificial intelligence (APS, 2025).

The concept of quantum computational advantage is central to the ongoing race between nations to harness the full power of quantum mechanics. Countries like the United States and China have been in a head-to-head competition, each achieving breakthroughs that push the boundaries of what is computationally possible. In 2019, Google’s Sycamore processor claimed the first demonstration of quantum supremacy, and in 2020 China’s Jiuzhang prototype followed suit. Now, with Zuchongzhi 3.0, China has once again set a new record in superconducting quantum systems (China Daily, 2025).

The Technology Behind Zuchongzhi 3.0

Developed by a team of prominent Chinese quantum physicists—including Pan Jianwei, Zhu Xiaobo, and Peng Chengzhi—the Zuchongzhi 3.0 system builds upon the success of its predecessor, Zuchongzhi 2.1, which featured 66 qubits. The new prototype leverages advances in superconducting materials, circuit design, and noise reduction techniques to achieve higher qubit coherence and reliability. With 105 qubits arranged in a precise configuration and 182 couplers facilitating qubit interaction, the device demonstrates state-of-the-art performance in executing complex quantum operations (CGTN, 2025).

One of the key performance metrics is the speed at which Zuchongzhi 3.0 performs quantum random circuit sampling. This task, which involves applying a sequence of randomly ordered quantum gates to a set of qubits and measuring the resultant state, is used to showcase the computational might of quantum devices. According to reports, the new prototype completes these tasks at a speed that is quadrillion times faster than the fastest classical supercomputer and one million times faster than Google’s benchmark results published as recently as October 2024 (Global Times, 2025). Such staggering performance figures are made possible by significant improvements in qubit control, error rates, and overall system integration.

The device’s architecture also marks a significant upgrade in its capability for error correction and scalability. Quantum error correction remains one of the most critical challenges in the field, and the Zuchongzhi 3.0 research team is actively exploring methods such as surface code error correction. By experimenting with code distances of 7, 9, and 11, the team aims to pave the way for large-scale qubit integration—a necessary step for the eventual development of programmable, general-purpose quantum computers (IEEE Spectrum, 2022).

Comparing Global Quantum Efforts

China’s latest breakthrough does not exist in isolation. The global quantum computing community is witnessing rapid advances from multiple corners. In the United States, Google’s Sycamore and its successors have set high benchmarks for quantum computational advantage. Meanwhile, research teams around the world are tackling different technical challenges—some focusing on scaling the number of qubits, while others emphasize fault-tolerance and error correction.

For example, while Google’s work has concentrated on demonstrating quantum supremacy with processors like Sycamore and its subsequent models, Chinese teams have strategically focused on enhancing qubit fidelity and the overall integration of superconducting systems. The Zuchongzhi series, now in its 3.0 iteration, is a testament to China’s commitment to pushing hardware limits. Each breakthrough serves as both a milestone and a motivator for further innovation. This technological rivalry has led to a dual-path approach in quantum research: one path seeks to maximize raw computational power, while the other refines the quality and stability of qubit operations.

In recent experiments, Zuchongzhi 3.0 has demonstrated that even when compared with other leading prototypes, such as Google’s latest offerings, its performance in specific benchmark tasks remains unmatched.
