Quantum computing is a type of computing that uses quantum mechanics to process information in ways traditional computers cannot. Unlike classical bits, which represent data as either 0 or 1, quantum bits (qubits) can exist in multiple states simultaneously, thanks to phenomena like superposition and entanglement. This enables quantum computers to solve complex problems, such as simulating molecules or optimizing large systems, much faster than classical computers. While still in the early stages of development, quantum computing has the potential to revolutionize fields like cryptography, medical discovery, and artificial intelligence.
