  • Abbreviation of quantum bit. An individual particle utilized to store information. Particles, which obey the laws of quantum mechanics, can have their spin influenced for storage, and detected for retrieval. A single qubit can be used to represent a one, a zero, or both, with a coefficient representing the probability for each state. Two qubits can represent every two-bit number, which specifically are 00, 01, 10, and 11. Each additional qubit increases the number representation exponentially, at a rate of 2n, where n is the number of qubits. For example, 50 qubits can represent every number between zero and beyond a quadrillion.
