qiskit.circuit.Qubit

class Qubit(register=None, index=None)

Implement a quantum bit.

Creates a qubit.

Parameters

register (QuantumRegister) – Optional. A quantum register containing the bit.
index (int) – Optional. The index of the bit in its containing register.

Raises

CircuitError – if the provided register is not a valid QuantumRegister

__init__(register=None, index=None)

Creates a qubit.

Parameters

register (QuantumRegister) – Optional. A quantum register containing the bit.
index (int) – Optional. The index of the bit in its containing register.

Raises

CircuitError – if the provided register is not a valid QuantumRegister
