On this episode of Quantum Computing Business, Lucas and Luna examine a quiet but significant shift in banking: how quantum annealers and hybrid classical-quantum workflows are starting to redraw the way regulators and lenders run stress tests. They anchor the conversation in a 2025 pilot in which a major European bank used a quantum-classical hybrid to run thousands of portfolio scenarios in a fraction of the time taken by classical models, cutting a two-week exercise down to under an hour. The hosts break down the difference between Monte Carlo simulation and quantum sampling, explain why correlation matrices are the trickiest part, and confront the validation problem — how do you prove a quantum result is sound when you can't check it against a classical baseline? They also look at what this means for the next round of Basel III implementation and the growing market for quantum-as-a-service in finance. If you are building or running a business in banking, risk, or fintech, this episode gives you one concrete number and one concrete idea you can bring to a conversation today.
