qubit(QUantum BIT) A data bit in quantum computing. Such an entity can hold more than two values. See quantum computing. qubit [′kyü·bit] (computer science) In quantum computation, a superposition of the ground state and the excited state of an elementary two-level quantum system (such as a two-level atom or a nuclear spin), corresponding to a classical bit that is either 0 (corresponding to the ground state) or 1 (corresponding to the excited state).

With such data, scientists may learn to use those boxed-up electrons as basic components, or qubits, of quantum computers--machines expected to exploit quantum physics to vastly outperform current computers in certain calculations (SN: 2/22/03, p. This work provides valuable guidance for future Qubit development by demonstrating the need for materials research directed at reducing critical-current fluctuations in tunnel junctions. we've transferred a matter qubit to a photon qubit," Kuzmich says. |
