Bit#

class qiskit.circuit.Bit(register=None, index=None)[source]#

Bases : object

Implement a generic bit.

Note

This class should not be instantiated directly. This is just a superclass for Clbit and Qubit.

Create a new generic bit.

Attributes

index#

Get the index of an old-style bit in the register that owns it.

In modern Qiskit Terra (version 0.17+), bits are the fundamental object and registers are aliases to collections of bits. A bit can be in many registers depending on the circuit, so a single containing register is no longer a property of a bit. It is an error to access this attribute on bits that were not constructed as « owned » by a register.

Obsolète depuis la version 0.17: The property qiskit.circuit.bit.Bit.index is deprecated as of qiskit-terra 0.17. It will be removed no earlier than 3 months after the release date. Instead, use find_bit() to find all the containing registers within a circuit and the index of the bit within the circuit.
