基于IBM提供的qiskit庫進行量子計算模擬
以下為安裝指令
pip install qiskit
請使用https源例如清華源執(zhí)行pip安裝
Windows 換源方法 - 創(chuàng)建文件 User/YourUserName/pip/pip.ini 內(nèi)容如下

以下為示例代碼
import numpy as np
from qiskit import(
QuantumCircuit,
execute,
Aer)
from qiskit.visualization import plot_histogram
# Use Aer's qasm_simulator
simulator = Aer.get_backend('qasm_simulator')
# Create a Quantum Circuit acting on the q register
circuit = QuantumCircuit(2, 2)
# Add a H gate on qubit 0
circuit.h(0)
# Add a CX (CNOT) gate on control qubit 0 and target qubit 1
circuit.cx(0, 1)
# Map the quantum measurement to the classical bits
circuit.measure([0,1], [0,1])
# Execute the circuit on the qasm simulator
job = execute(circuit, simulator, shots=1000)
# Grab results from the job
result = job.result()
# Returns counts
counts = result.get_counts(circuit)
print("\nTotal count for 00 and 11 are:",counts)
# Draw the circuit
circuit.draw()
預期輸出
Total count for 00 and 11 are: {'11': 500, '00': 500}
