pysimplex 1.5.0

A fast Clifford circuit simulator

pysimplex

This is a fast Clifford circuit simulator based on BH21.

Wheels are currently available for Linux, MacOS and Windows, for Python versions 3.8, 3.9 and 3.10.

Example usage:

from pysimplex import Simplex
S = Simplex(2) # a 2-qubit system
S.H(0).CX(0, 1)
b0 = S.MeasZ(0, coin=0) # 'coin' is an optional argument that fixes the result
assert b0 == 0 # without 'coin' it would be 0 or 1 with equal probability
b1 = S.MeasZ(1)
assert b0 == b1
assert not S.is_deterministic() # 'coin' is irrelevant here

The available operations are: X, Y, Z, H, S, Sdg, CX, CZ, MeasX, MeasY and MeasZ. The global phase (in units of pi/4, modulo 8) can be retrieved with the phase property.
