Understanding Quantum Computing: How It Differs from Classical Computing
Quantum computers leverage quantum bits (qubits) rather than binary bits (0s and 1s), enabling them to process multiple states simultaneously through quantum phenomena such as superposition and entanglement.
Key differences between classical and quantum computing include
- Superposition: Qubits exist in multiple states at once, exponentially increasing computing power.
- Entanglement: Qubits communicate instantly, enabling faster information processing.
- Quantum parallelism: Unlike classical processors that perform calculations sequentially, quantum computers solve complex problems in parallel.
These properties make quantum computing ideal for solving optimization problems, accelerating AI algorithms, and breaking encryption protocols.
