BGLS

BGLS是一个Python包，实现了在《如何在不计算边缘的情况下模拟量子测量》（Phys. Rev. Lett.）（arXiv）中提出的Bravyi, Gosset和Liu采样算法，用于Cirq电路。

快速入门

安装

pip install bgls

示例

import cirq
import bgls

# Example circuit to run.
qubits = cirq.LineQubit.range(2)
circuit = cirq.Circuit(
    cirq.H.on(qubits[0]),
    cirq.CNOT.on(*qubits),
    cirq.measure(*qubits, key="z")
)

# Run the circuit with BGLS.
simulator = bgls.Simulator(
    initial_state=cirq.StateVectorSimulationState(qubits=qubits, initial_state=0),
    apply_op=cirq.protocols.act_on,
    compute_probability=bgls.born.compute_probability_state_vector,
)
results = simulator.run(circuit, repetitions=10)
print(results.histogram(key="z"))

示例输出

Counter({0: 6, 3: 4})
