What is Quantum Computing?
Quantum computing leverages the principles of quantum mechanics to process information in fundamentally different ways compared to classical computing. Unlike classical bits, which represent data as 0 or 1, quantum bits (qubits) can represent both 0 and 1 simultaneously through a property called superposition. Additionally, qubits can be entangled, meaning the state of one qubit can depend on the state of another, even when separated by large distances.
Key Concepts:
- Superposition: Allows qubits to be in multiple states at once, enabling parallel processing on a massive scale.
- Entanglement: Creates a link between qubits that allows instantaneous correlation of their states, facilitating faster information processing and transmission.
- Quantum Interference: Used to amplify correct solutions and cancel out incorrect ones during computation.
