Quantum State Discrimination
A fundamental task in quantum information processing that infers quantum state labels from measurement signals, subject to the Bayesian risk lower bound.
Timeline (last 90 days)
On superconducting hardware, the reliability of mid-circuit measurement has long been constrained by noise, and its operation depends on precise quantum state discrimination.
The performance ceiling of quantum state discrimination is determined by the signal-to-noise ratio and the degree of distribution overlap of the readout signal itself, rather than by the classifier algorithm.
