1. What Is Quantum Computing?
Quantum Computing uses the laws of quantum mechanics to process data.
Unlike traditional computers that rely on bits (0 or 1), quantum computers use qubits — which can exist as 0, 1, or both at once through superposition.
This allows quantum machines to perform massively parallel computations, solving problems that classical computers would take millions of years to process.
💡 In short: Quantum computing is like exploring every possible answer to a problem — all at once.
2. How Quantum Computers Work
Quantum computers harness two core principles:
Key Concepts
- Superposition: Enables qubits to hold multiple states simultaneously.
- Entanglement: Links qubits so that changing one affects another instantly.
- Quantum Interference: Filters out incorrect answers while amplifying correct ones.
Together, these allow for exponential computation speed and accuracy.
💡 Example: While a classical computer checks each password one by one, a quantum computer evaluates all possibilities in parallel.
3. Quantum vs. Classical Computing
| Feature | Classical Computing | Quantum Computing |
|---|---|---|
| Data Unit | Bit (0 or 1) | Qubit (0, 1, or both) |
| Processing | Sequential | Parallel |
| Power | Linear | Exponential |
| Use Case | Everyday computing | Complex problem-solving |
💡 Quantum computers won’t replace classical ones — they’ll augment them for ultra-complex calculations.
