Cirq is a Python library for writing, manipulating, and optimizing quantum circuits and running them against quantum computers and simulators.
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.from_ops( 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.google.XmonSimulator() result = simulator.run(circuit, repetitions=20) print("Results:") print(result)
Circuit: (0, 0): ───X^0.5───M('m')─── Results: m=11000111111011001000
