What is Quantum Computing?

Quantum computing is a new field of computer science that utilizes the principles of quantum mechanics to perform calculations. Unlike classical computers, which rely on bits that can only exist in two states (0 or 1), quantum computers leverage qubits. Qubits can exist in a state of superposition, meaning they can be 0, 1, or both simultaneously. This unique property of qubits allows quantum computers to process significantly larger and more complex datasets than classical computers.
