Imagine you’re at an all-you-can-eat buffet.
The challenge?
Fill your plate with just the right mix of foods—enough protein, the right amount of carbs, something green to convince yourself it’s healthy—all while making sure it tastes amazing.
Now, imagine trying to do this whilst at a crazy robotic buffet the constantly changes, with dishes appearing and disappearing at random at different prices and different yield’s.
That, my friends, is what portfolio management feels must feel like.
Portfolio Optimisation is a Hard Computational Problem
The process involves selecting the optimal mix of assets while considering risk, return, and correlation. This is known as the Markowitz Mean-Variance Optimisation Model (1952), which laid the foundation for modern portfolio theory.
The challenge? As the number of assets increases, the number of possible portfolio combinations grows exponentially, making it a computational nightmare for classical computers. Reference: Markowitz, H. (1952). Portfolio Selection. The Journal of Finance, 7(1), 77-91.
- Markets Are Constantly Changing
- Quantum Computing’s Advantage in Portfolio Optimisation
It’s a delicate dance of choosing the perfect mix of investments to maximise returns and reduce risks—without ending up with a financial bellyache.
Portfolio Optimisation Will Change
Traditional investing strategies use computer models to crunch numbers and tell you the best way to invest your money.
The problem?
These models rely on simplified assumptions and trial-and-error calculations.
Quantum technology swoops in at some point in the near future, like a superhero thats late for the party.
Whilst quantum computing is still in its early adopter stage, at the point of Quantum Realisation
Why Quantum?
Normal computers tackle portfolio optimisation by checking one investment mix at a time, a bit like flipping through every possible song combination to make the perfect playlist. Quantum computers? They check them all at once.
Think of it like this: If a classical computer is a detective interrogating suspects one by one, a quantum computer is a psychic detective who instantly knows whodunnit without breaking a sweat.
The result? Faster, more precise investment strategies. You get: ✔ Better portfolio performance ✔ Reduced financial risk ✔ A system that adapts in real-time to market changes
Who’s Leading the Charge?
This isn’t sci-fi—it’s already happening.
🔹 JP Morgan is using the Harrow-Hassidim-Lloyd (HHL) algorithm alongside hybrid high-performance computing and trapped-ion quantum systems. If you don’t know what that means, don’t worry—just know it’s serious stuff. The team spearheading this includes Romina Yalovetzky, Dylan Herman, and Marco Pistoia from Global Technology Applied Research.
🔹 Raiffeisen Bank International is testing D-Wave’s quantum systems, stating that they’re already handling complex financial calculations with these machines.
Where Are We Now?
Quantum-powered portfolio management isn’t fully mainstream—yet. Right now, the technology is in early-stage lab testing. Think of it as the Wright brothers testing their first aeroplane—it’s not a commercial flight yet, but we all know where this is heading.
At this stage, we’re seeing hybrid environments, where quantum computers work alongside AI and supercomputers to deliver impressive results.
The Business Advantage: Beating the Market Before Breakfast
💡 Before Quantum: Analysts take weeks to crunch numbers and build an investment strategy. Then, they cross their fingers and hope the market doesn’t shift overnight.
🚀 After Quantum: Portfolio optimisation becomes a real-time process. Instead of outdated reports, investors get instant strategies, dynamically adapting to market trends automatically.
Banks that jump on this first? They’ll have an industry-shaking advantage. Imagine being able to predict and react to market movements before competitors even get out of bed.
