Module bit 

Qubit Module

This module defines the fundamental addressing units for quantum circuits.

Architecture Design

This library adopts a Handle Pattern (also known as Entity-Component style) for qubit management:

• Qubit acts as a lightweight, Copy-able logical identifier. It does not hold state or topological information itself.
• State and connectivity are managed by the parent Circuit or DAG.

This design ensures strictly $O(1)$ cloning costs and cache-friendly memory layouts during complex compilation passes.

Structs

Qubit

Enums

QubitError

Errors returned when converting an integer into a Qubit.
