Quantum Update
One short letter a month on quantum computing for financial services: measured results from the Rapid Quantum Prototypes, published studies, and the occasional regulatory clock — wins and losses alike. Evidence, not promises.

Our circuits on a real quantum processor
September 2026- Real progress on reliable qubits — 30 logical qubits from 80 atoms, and the fine print between detecting and correcting errors
- The promised hardware story: five trained circuits on ibm_kingston, what survived, and why calibration forecasts are optimistic ceilings
- Code exports across all Rapid Quantum Prototypes: Qiskit, PennyLane, Cirq, CUDA-Q, Classiq Qmod — test before you port
- Two configuration atlases published, and a day at the QAI Ventures summit in Basel

IBM's "advantage", and what a referee makes of it
August 2026- IBM's quantum-advantage demonstrations and the NZZ counter-view — why both are useful
- The QAOA concentration study: ~12,400 certified runs, and a decision tree instead of a method
- Two new RQPs: Credit Allocation Pro and Robust Stochastic Collateral Allocation
- A quantum circuit that builds itself — the adaptive ansatz as a second opinion
