Quantum computing and classical computing represent two distinct paradigms in computational science. Here's a breakdown of their key differences:
🔍 Core Principles
- Classical Computing: Relies on bits (0 or 1) and Boolean logic gates.
- Quantum Computing: Uses qubits that leverage superposition and entanglement.
⚡ Performance & Scalability
| Feature | Classical | Quantum |
|---|---|---|
| Parallelism | Limited to bitwise parallelism | Enables quantum parallelism |
| Speed for specific tasks | Slower for complex simulations | Exponentially faster for certain problems (e.g., factorization) |
🌐 Applications
- Classical: Dominates everyday tasks like web browsing, data storage, and classical cryptography.
- Quantum: Shows promise in fields like drug discovery, optimization, and breaking encryption.
