qrisp.QuantumCircuit.from_qiskit#

classmethod QuantumCircuit.from_qiskit(qiskit_qc)[source]#

Class method to create QuantumCircuits from Qiskit QuantumCircuits.

Parameters:

qiskit_qcQiskit QuantumCircuit: The Qiskit QuantumCircuit to convert.

Returns:

QuantumCircuit: The converted QuantumCircuit.

Examples

We construct a fan-out QuantumCircuit in Qiskit:

>>> from qiskit import QuantumCircuit as QiskitQuantumCircuit
>>> qc_2 = QiskitQuantumCircuit(4)
>>> qc_2.cx(0, range(1,4))
>>> print(qc_2)

q_0: ──■────■────■──
     ┌─┴─┐  │    │
q_1: ┤ X ├──┼────┼──
     └───┘┌─┴─┐  │
q_2: ─────┤ X ├──┼──
          └───┘┌─┴─┐
q_3: ──────────┤ X ├
               └───┘

Note that we don’t need to create a QuantumCircuit object first as this is a class method.

>>> from qrisp import QuantumCircuit
>>> qrisp_qc_2 = QuantumCircuit.from_qiskit(qc_2)
>>> print(qrisp_qc_2)
