Quantum computing represents a paradigm shift from classical binary computing by leveraging quantum mechanical phenomena to process information. Unlike traditional bits that exist in either 0 or 1 states, quantum bits (qubits) can exist in multiple states simultaneously through a property called superposition.
The National Institute of Standards and Technology defines quantum computing as a technology that harnesses quantum mechanical properties to perform calculations that are intractable for classical computers. This revolutionary approach enables exponential scaling of computational power for specific problem types.
