Bonaparte Quantum Foundations

Bit vs. Qubit

In classical computing, a bit can only exist in one of two states: 0 or 1. In quantum computing, a qubit can exist in a superposition of both states simultaneously, represented as α|0⟩ + β|1⟩. When measured, it collapses to either 0 or 1.

Key Differences and Concepts:

  • Classical Bit: Always 0 or 1.
  • Qubit: Exists in a superposition of 0 and 1, until measured.
  • Visualization: Represented on a Bloch sphere, showing infinite possible states.
  • Key Concept: Superposition enables quantum parallelism.
Classical vs. Quantum Representation
Classical computers store a definite 0 or 1, while quantum computers’ qubits (Quantum Bit) can spin in superposition — a mix of both — until they collapse when measured.
