Register

class qiskit.circuit.Register(size=None, name=None, bits=None)

Implement a generic register.

Note

This class should not be instantiated directly. This is just a superclass for ClassicalRegister and QuantumRegister.

Create a new generic register.

Either the size or the bits argument must be provided. If size is not None, the register will be pre-populated with bits of the correct type.

Parameters

size (int) – Optional. The number of bits to include in the register.
name (str) – Optional. The name of the register. If not provided, a unique name will be auto-generated from the register type.
bits (list[Bit]) – Optional. A list of Bit() instances to be used to populate the register.

Raises

CircuitError – if both the size and bits arguments are provided, or if neither are.
CircuitError – if size is not valid.
CircuitError – if name is not a valid name according to the OpenQASM spec.
CircuitError – if bits contained duplicated bits.
CircuitError – if bits contained bits of an incorrect type.
