Qblaze

An open-source simulator for quantum circuits and quantum programs that addresses slow and memory-intensive simulation of workloads with sparse and dense state vectors. It is for developers and engineering teams building, testing, and benchmarking quantum algorithms in research and business settings. It is positioned as a sparse state vector simulator that demonstrates orders-of-magnitude performance improvements over existing simulators while remaining competitive on dense workloads, delivered as open-source software with APIs for C, Python, and Rust and drop-in support for Qiskit.
