Major improvements have been made on semiconductor quantum dot light sources recently and now they can be seen as a serious candidate for near-future scalable photonic quantum information processing experiments. The three key parameters of these photon sources for such applications have been pushed to extreme values: almost unity single-photon purity and photon indistinguishability, and high brightness. In this paper, we review the progress achieved recently on quantum-dot-based single-photon sources. We also review some quantum information experiments where entanglement processes are achieved using semiconductor quantum dots.
近年来,半导体量子点光源取得了重大进展,现在它们可被视为近期可扩展光子量子信息处理实验的有力候选者。这些用于此类应用的光子源的三个关键参数已被推至极值:几乎为1的单光子纯度和光子不可区分性,以及高亮度。在本文中,我们回顾了基于量子点的单光子源最近取得的进展。我们还回顾了一些使用半导体量子点实现纠缠过程的量子信息实验。
