Quantum Software Stacks Get Differential Tests
QDiff generates semantics-preserving program variants, filters costly circuits and compares probabilistic outputs.
Summary
QDiff generates semantics-preserving program variants, filters costly circuits and compares probabilistic outputs.
The framework uses static circuit properties to avoid uninformative hardware runs and supports distribution comparisons including Kolmogorov–Smirnov tests and cross entropy. The paper proposes and evaluates a testing method; it does not certify any whole quantum stack as defect-free.
Why it matters
