Explain quantum computing in simple terms

Quantum computing is a type of computing that uses quantum bits, or qubits, which can exist in multiple states at the same time. This allows quantum computers to perform calculations that would take traditional computers a very long time to solve. Quantum computers use principles of quantum mechanics to process information and solve problems, making them incredibly powerful tools for solving complex problems in fields like cryptography, finance, and science. However, quantum computing is still in its early stages and is not yet widely available or understood.
