PennyLane-Lightning

PennyLane-Lightning provides high-performance C++ quantum simulators that integrate as plugins with the PennyLane quantum machine learning library. The base package includes the `lightning.qubit` device for CPU-based state-vector simulation, with other specialized devices (GPU, Kokkos, Tensor, AMDGPU) available via separate installation packages. It is actively maintained with frequent, typically monthly or bi-monthly, releases.
