Abstract

In this paper, we have developed a design of a quantum device which is capable of distributed quantum information processing. An negatively charged NV center is imbedded in a optical cavity, of which resonance is tuned to realize dipole induced transparency dependent on the electron state in the NV center. This quantum device is then connected via optical fiber, and is assembled to perform arbitrary large quantum information tasks in a distributed manner.In this presentation, we discuss these physical imperfections and their effects to the performance of the quantum information processing. Then we show how we can control them to achieve the accuracy for the information task at hand.
