Quantum Computing

Short Answer
Quantum computing leverages quantum mechanics to perform computations exponentially faster than classical computers.

Quantum Computing

Definition

Quantum computing harnesses principles of quantum mechanics, such as superposition and entanglement, to process information using quantum bits or qubits. Unlike classical bits that represent either 0 or 1, qubits can exist in both states simultaneously due to superposition, enabling parallel processing. This potential allows quantum computers to solve complex problems exponentially faster than classical computers. Algorithms like Shor's algorithm for factoring large numbers and Grover's algorithm for searching unsorted databases demonstrate quantum computing's potential for cryptography, optimization, and artificial intelligence. Challenges include qubit stability, error correction, and scaling to practical applications.
