Quantum computing is a revolutionary field that harnesses the principles of quantum mechanics to process and store information in a fundamentally different way than classical computing. At its core, quantum computing leverages the unique properties of quantum bits, or qubits, which can exist in multiple states simultaneously thanks to the phenomenon of superposition. This allows quantum computers to perform complex calculations at an exponentially faster rate than classical computers, making them well-suited for tackling problems that are currently intractable with traditional computing methods.
