Haiqu and HSBC just showed quantum computing doing something useful in finance on real IBM hardware

Haiqu and HSBC demonstrated a new method for encoding financial data into a quantum computer, tested on IBM Quantum hardware scaling up to 156 qubits. The technique targets a specific problem in risk assessment: modelling the kind of rare but catastrophic events that standard statistical tools handle poorly. Rather than a lab toy benchmark, this is aimed squarely at derivative pricing and the kind of tail-risk calculations that banks genuinely care about. It is an early result and real commercial deployment is still some way off, but it is notable because it is a concrete financial use case running on hardware you can actually access today.

Finally a finance quantum story that is not just portfolio optimisation vaporware. Modelling rare catastrophic events is exactly where classical statistics struggles

156 qubits on IBM hardware is not a toy experiment anymore. This is getting into territory where the numbers could actually mean something

A bank being involved does not automatically make something real. Would want to see independent replication before getting excited

Derivative pricing with better tail-risk modelling could save or lose billions. If quantum gets even a small edge here the investment will pay for itself fast
