What is Quantum Computing?

Quantum computing is a new computing paradigm that uses quantum bits (qubits) instead of classical bits.

• Classical bits store data as either 0 or 1
• Qubits can exist as 0, 1, or both simultaneously

This unique capability allows quantum computers to process massive amounts of data in parallel, enabling unprecedented computational power.

Core Principles of Quantum Computing

Superposition

A qubit can represent multiple states at the same time, dramatically increasing computational capacity.

Entanglement

Qubits can be interconnected so that the state of one qubit instantly influences another, even across large distances.

Quantum Interference

Quantum systems amplify correct results while canceling out incorrect ones during computation.
