devqubit-cirq 0.1.12

devqubit adapter for Cirq

devqubit-cirq

Google Cirq adapter for devqubit — automatic circuit capture, simulator snapshots, and result logging for Cirq samplers and simulators.

[!IMPORTANT] This is an internal adapter package. Install via pip install "devqubit[cirq]" and use the devqubit public API.

Installation

pip install "devqubit[cirq]"

Usage

import cirq
from devqubit import track

q0, q1 = cirq.LineQubit.range(2)
circuit = cirq.Circuit([
    cirq.H(q0),
    cirq.CNOT(q0, q1),
    cirq.measure(q0, q1, key="result"),
])

with track(project="cirq-exp") as run:
    simulator = run.wrap(cirq.Simulator())
    result = simulator.run(circuit, repetitions=1000)

Parameter Sweeps

import sympy

theta = sympy.Symbol("theta")
circuit = cirq.Circuit([
    cirq.Ry(theta).on(q0),
    cirq.measure(q0, key="m"),
])

with track(project="sweep") as run:
    simulator = run.wrap(cirq.Simulator())
    sweep = cirq.Linspace("theta", 0, 2 * 3.14159, 10)
    results = simulator.run_sweep(circuit, sweep, repetitions=100)
