qiskit-quimb

使用Qiskit电路通过quimb进行模拟。

安装

pip install qiskit-quimb

用法

qiskit_quimb模块公开了两个函数

• quimb_circuit：将Qiskit电路转换为quimb电路。这可能是您想要使用的函数。
• quimb_gates：将Qiskit电路转换为quimb门列表，这更加灵活。

示例代码

import quimb.tensor
from qiskit.circuit import QuantumCircuit, QuantumRegister
from qiskit_quimb import quimb_circuit

# Build a Qiskit circuit
qubits = QuantumRegister(2)
circuit = QuantumCircuit(qubits)
a, b = qubits
circuit.h(a)
circuit.cx(a, b)

# Convert it to a quimb circuit
quimb_circ = quimb_circuit(circuit)

# Sample 10 bitstrings
samples = list(quimb_circ.sample(10, seed=1234))
print(samples)

# You can specify the quimb Circuit subclass and keyword arguments for the constructor
quimb_circ = quimb_circuit(
    circuit, quimb_circuit_class=quimb.tensor.CircuitMPS, max_bond=20
)
samples = list(quimb_circ.sample(10, seed=1234))
print(samples)
