The project aims at making a significant step towards elements for optical quantum information processing. Defect centers in nano-crystalline diamond serve as individual quantum systems providing photons and spin degrees of freedom that can be coupled and manipulated on integrated on-chip quantum circuits. The ultimate purity limit of single-photons from defect centers in diamond nano-crystals will be explored and efficient coupling to integrated on-chip quantum circuits will be studied. The goal is to perform first on-chip quantum gates. Another objective concerns quantum control of few-photon light and optical read-out of single defect centers in strongly confined optical fields. Finally, integrated nanophotonics will be exploited for high-fidelity initialization, manipulation, and single shot read-out of the defect center's spin degree of freedom.

该项目旨在朝着光量子信息处理元件迈出重要一步。纳米晶体金刚石中的缺陷中心充当单独的量子系统，提供光子和自旋自由度，可以在集成的片上量子电路上耦合和操纵。我们将探讨钻石奈米晶体中缺陷中心的单光子的纯度极限，并研究其与晶片上整合量子电路的有效耦合。目标是实现第一个片上量子门。另一个目标涉及在强限制光场中的少光子光的量子控制和单个缺陷中心的光学读出。最后，集成纳米光子学将被用于高保真初始化，操作和缺陷中心的自旋自由度的单次读取。
