1. Introduction

Quantum computing leverages quantum mechanics to solve problems that classical computers cannot. Unlike classical bits (qubits), quantum bits can represent 0, 1, or both simultaneously, enabling exponentially faster computations.

1.1 Differences Between Classical and Quantum Computers

1. Classical computers use binary bits, while quantum computers use qubits.
2. Qubits enable parallel processing through superposition.
3. Quantum computers excel in solving specific complex problems.
4. Classical computers are stable, while quantum systems are prone to errors.
5. Quantum computers require environments near absolute zero to function.
