Clbit

class Clbit(register=None, index=None)

ベースクラス: Bit

Implement a classical bit.

Creates a classical bit.

パラメータ

• register (ClassicalRegister) – Optional. A classical register containing the bit.

• index (int) – Optional. The index of the bit in its containing register.

例外

CircuitError – if the provided register is not a valid ClassicalRegister

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.

バージョン 0.17 で非推奨: 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.
