Explain quantum computing in simple terms.
Quantum computing is a type of computing that uses quantum bits, or 'qubits'. Unlike traditional computers that use bits (1s and 0s) to process information, quantum computers use qubits, which can exist in multiple states at once. This allows them to perform many calculations simultaneously, making them potentially much more powerful than traditional computers for certain tasks. However, they're still in the early stages of development and are currently not very practical for most real-world applications.
