| 摘要 |
An apparatus includes a material in a resonator and containing systems, each of the systems having five energy states, a unit generating first and second pulse that resonate in a second transition and a third transition, respectively, a unit controlling the first and second pulse to make the first and second pulse temporally overlap each other to obtain third light, a unit emitting the third light to each system, a unit generating observation light to be coupled to the resonator mode, a unit introducing the observation light to the resonator from an outside thereof, a unit reading one of quantum bits by measuring an intensity of one of reflected light and transmitted light of the observation light, a unit controlling the first and second pulse to make the first and second pulse temporally overlap each other to obtain fourth light, and a unit emitting the fourth light to each system.
