aleph-sim 0.2.0

High-performance quantum circuit simulator in Rust: state-vector, MPS, and stabilizer backends

aleph-sim

aleph is a high-performance quantum circuit simulator written in Rust, with pluggable backends: full state-vector (SIMD + multi-threaded), MPS (matrix product state), and stabilizer (tableau). It is benchmarked against Qiskit Aer (state vector + MPS) and Stim (stabilizer) — every parity-matrix cell is at or below 1.2× its reference, most well below 1× (aleph faster); see the parity report.

Install

pip install aleph-sim

The package is named aleph-sim (the name aleph is taken on PyPI); the Python module is still import aleph. Wheels: Linux x86_64 (manylinux_2_28) and macOS arm64, Python ≥ 3.12 (abi3). They are also attached to each GitHub release.

Quickstart

import aleph

c = aleph.Circuit(2)
c.h(0)
c.cx(0, 1)

result = aleph.run(c, shots=1024, seed=0)
print(result.counts())        # {'00': ~512, '11': ~512}
print(result.statevector())   # 4 amplitudes
