Storage and conduction of quantum information

Methods and apparatus for storing and conducting quantum information provide a luminescent center in silicon that is controllably coupled to experience a quantum interaction with a first qubit, such as a superconducting qubit. For example, the luminescence center may be a T-center or a T-center system. The same or different quantum information may be stored by one or more of non-paired electron or hole spins and/or three nuclear spins of the T-center. The stored quantum information may later be returned to the first qubit or communicated to a visible sub-state. 用于存储及传导量子信息的方法及设备提供硅中的发光中心，所述发光中心经可控地耦合以经历与例如超导量子位的第一量子位的量子相互作用。举例来说，所述发光中心可为T中心或T中心系集。可以所述T中心的不成对电子或空穴自旋及/或三个核自旋中的一或多者存储相同或不同量子信息。稍后可将所述经存储量子信息返回到所述第一量子位或传送到可见光子状态。
