Quantum Computing

Definition

Quantum computing is a revolutionary type of computation that uses the principles of quantum mechanics to process information. Unlike classical computers, which use bits as the smallest unit of data represented as either 0 or 1, quantum computers utilize quantum bits or qubits, which can exist in multiple states simultaneously. This capability allows quantum computers to perform complex calculations much faster than traditional computers, potentially transforming fields such as cryptography, optimization, and materials science.
