Welcome to the official GitHub organization of TensorCircuit, hosting the high-performance quantum software framework TensorCircuit-NG, as well as the toolchains and ecosystem surrounding the TensorCircuit-NG infrastructure.

More than just a simulator, TensorCircuit-NG is built to be the foundational infrastructure for the next era of computing. In essence, it serves as the JAX for differentiable quantum programming, the CUDA for massive HPC acceleration, and the operating system (OS) for autonomous scientific agents.
