Qubits, or quantum bits, are the fundamental units of quantum information in quantum computing, analogous to classical bits but with distinct properties due to the principles of quantum mechanics. Unlike classical bits, which can represent a state of 0 or 1, qubits can exist in superpositions of states, allowing them to perform complex calculations much faster than classical computers. This unique ability to represent multiple states simultaneously makes qubits essential for advancing technologies in quantum computing and information processing.
congrats on reading the definition of qubits. now let's actually learn it.
