Qubits, or quantum bits, are the fundamental units of information in quantum computing, analogous to classical bits but with unique properties that allow them to exist in multiple states simultaneously. Unlike classical bits, which can be either 0 or 1, qubits can represent both 0 and 1 at the same time due to a phenomenon called superposition. This property enables qubits to perform complex computations more efficiently and opens up exciting possibilities for applications in various fields.
congrats on reading the definition of qubits. now let's actually learn it.
