QuantRS2 0.2.1 Released — A Correct Rz Gate, Phase Estimation From Hours to Milliseconds, and Pure-Rust CUDA
QuantRS2 0.2.1 fixes a real correctness bug — Rz/CRZ/ParametricRotationZ now follow the IBM/Qiskit/OpenQASM-3 sign convention, caught by independent symbolic verification — cuts Quantum Phase Estimation from hours to milliseconds, lands real D-Wave chain-break decoding and AWS Braket SigV4 signing, and adds a pure-Rust oxicuda backend.
