How Does Quantum Computing Work?
1. Qubits – The Foundation of Quantum Computing
- Unlike classical bits (which are either 0 or 1), qubits exist in multiple states at once (superposition).
- Example: A single qubit can be in both 0 and 1 simultaneously.
2. Superposition – Multiple States at Once
- Classical computers compute one step at a time, while quantum computers process multiple possibilities simultaneously.
3. Entanglement – Quantum Connectivity
- When two qubits become entangled, changing the state of one instantly affects the other, no matter the distance.
- This enables ultra-fast communication and problem-solving.
