摘要:

我们提出了一个基本的构建块的量子网络组成的量子点耦合到一个源腔,这反过来又耦合到一个目标腔通过波导。从高Q/V源腔的单光子发射的特征在于由一个12倍的自发发射(SE)率增强,导致在SE耦合效率接近0.98到源腔模式。单光子通过波导有效地转移到目标腔中,源/目标场强度比为0.12(在没有耦合量子点的其他结构中观察到高达0.49)。该系统显示出作为未来片上量子信息处理系统的构建块的巨大前景。

英文摘要:

We present a basic building block of a quantum network consisting of a quantum dot coupled to a source cavity, which in turn is coupled to a target cavity via a waveguide. The single photon emission from the high-Q/V source cavity is characterized by a twelve-fold spontaneous emission (SE) rate enhancement that results in a SE coupling efficiency near 0.98 into the source cavity mode. Single photons are efficiently transferred into the target cavity through the waveguide, with a source/target field intensity ratio of 0.12 (up to 0.49 observed in other structures without coupled quantum dots). This system shows great promise as a building block of future on-chip quantum information processing systems.
