There are many different types of bits and qubits, but all qubits must adhere to the laws of quantum physics and be able to exist in a quantum superposition. Unlike a classical bit, which can only exist in either a 0 or a 1 state, qubits can also occupy a superposition, representing 0, 1, and all intermediate states simultaneously. While qubits can encode multiple states at once, they are still used to convey information through a binary system. In such systems, the term “bit” can refer to either the material or process used to represent a 0 or 1, or the measurement of that bit itself.
