v0.1.0

Tsim is a GPU-accelerated quantum circuit sampler based on ZX-calculus stabilizer rank decomposition. It feels just like Stim, but supports non-Clifford gates.

Tsim is described in arXiv:2604.01059.

Highlights

• Clifford+T circuit simulation via stabilizer rank decomposition, following Sutcliffe and Kissinger (2024)
• Full Stim compatibility -- supports all Stim instructions, plus T, T_DAG, R_Z, R_X, R_Y, and U3
• Noise channels via parametric rewrites
• Arbitrary rotation gates via magic cat state decomposition from Qassim et al. (2021)
• GPU acceleration via JAX
• Documentation and tutorials at queracomputing.github.io/tsim

Installation

pip install bloqade-tsim

For GPU support:

pip install "bloqade-tsim[cuda13]"
