# Bit

*class* `qiskit.circuit.Bit(register=None, index=None)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.0/qiskit/circuit/bit.py#L21-L95)

Bases: [`object`](https://docs.python.org/3/library/functions.html#object)

Implement a generic bit.

> **Note**
>
> This class should not be instantiated directly. This is just a superclass for [`Clbit`](/docs/api/qiskit/1.0/qiskit.circuit.Clbit "qiskit.circuit.Clbit") and [`Qubit`](/docs/api/qiskit/1.0/qiskit.circuit.Qubit "qiskit.circuit.Qubit").

Create a new generic bit.
