Avenues for Quantum Error Correction and Mitigation
summary
Reports a provable limit for classical error mitigation: sample complexity scales like e^{system size × circuit width}, so zero-noise extrapolation needs exponentially many shots for growing circuits. Demonstrates experimental milestones: 48 logical qubits into 280 physical cold-atom qubits with active shuttling and a quantum‑error‑corrected microalgorithm run repeatedly, including real-time million runs of syndrome processing. Presents practical advances: existence of highly parallelizable decoders for QLDPC codes and schemes that reduce multi‑qubit checks to two‑qubit measurement schedules.
