This release is a pre-release and may not be stable for production use.
This is a development version of Cirq and may be unstable.
For the latest stable release of Cirq see here.
Cirq is a Python library for writing, manipulating, and optimizing quantum circuits and running them against quantum computers and simulators.
Installation and Documentation
Cirq documentation is available at cirq.readthedocs.io.
Documentation for the latest unstable version of cirq (tracks the repository’s master branch; what you get if you pip install cirq-unstable), is available at cirq.readthedocs.io/latest.
Documentation for the latest stable version of cirq (what you get if you pip install cirq) is available at cirq.readthedocs.io/stable.
Hello Qubit
A simple example to get you up and running:
import cirq
# Pick a qubit.
qubit = cirq.GridQubit(0, 0)
# Create a circuit
circuit = cirq.Circuit(
cirq.X(qubit)**0.5, # Square root of NOT.
cirq.measure(qubit, key='m') # Measurement.
)
print("Circuit:")
print(circuit)
# Simulate the circuit several times.
simulator = cirq.Simulator()
result = simulator.run(circuit, repetitions=20)
print("Results:")
print(result)Example output:
Circuit:
(0, 0): ───X^0.5───M('m')───
Results:
m=11000111111011001000Contributing

For those interested in using quantum computers to solve problems in chemistry and materials science, we encourage exploring OpenFermion and its sister library for compiling quantum simulation algorithms in Cirq, OpenFermion-Cirq.
Alpha Disclaimer
Cirq is currently in alpha. We are still making breaking changes. We will break your code when we make new releases. We recommend that you target a specific version of Cirq, and periodically bump to the latest release. That way you have control over when a breaking change affects you.
