Adaptive Quantum Tests Lost Their Asymptotic Edge
Parallel, adaptive and general channel testers reached the same Stein exponent at fixed type-I error.
Summary
Parallel, adaptive and general channel testers reached the same Stein exponent at fixed type-I error.
The theorem covers finite-dimensional memoryless quantum channels and identifies regularized channel relative entropy as the common asymptotic rate. The authors also derive the strong-converse exponent for general testers; this is a theoretical result rather than a hardware experiment.
Why it matters
Parallel, adaptive and general channel testers reached the same Stein exponent at fixed type-I error.
Limits and context
No additional limitation was separately recorded.
Key claims
Parallel, adaptive and general channel testers reached the same Stein exponent at fixed type-I error.
