qsim

qsim is a high-performance C++ state-vector simulator with a Python (qsimcirq) binding that plugs directly into Cirq. It is optimised for AVX/AVX-512, CUDA, and cuQuantum backends and is the default classical engine for benchmarking Cirq circuits at scales of 30+ qubits before submitting to hardware.
