Quantum Computing

What Is Quantum Computing?

Quantum computing is a groundbreaking field that utilizes the principles of quantum mechanics to process information in fundamentally different ways than classical computers. While classical computers use bits to process data as 0s or 1s, quantum computers leverage quantum bits or qubits that can exist in a state of 0, 1, or both simultaneously (superposition). This unique ability allows quantum computers to perform complex calculations at unprecedented speeds, thanks to phenomena such as superposition and entanglement.
