Quantum bits, or qubits, are the basic units of quantum information, analogous to classical bits in traditional computing. Unlike classical bits that can represent either a 0 or a 1, qubits can exist in a superposition of states, allowing them to represent both 0 and 1 simultaneously. This unique property enables quantum computers to perform complex calculations much faster than classical computers, making qubits essential for advancements in secure communication and cryptography.
