Generation of correlation-controlled entangled photons as a new light source

我们提出了利用半导体微腔高效地产生和控制具有量子关联的光子对的方法，并证明了与传统方法相比，利用该光子对可以实现高效的双光子激发。此外，我们还发现，通过控制光子对的量子关联，可以同时实现电子态的选择性激发和激发效率的提高。

We have proposed efficient-generation and control methods of a photon pair with quantum correlation using a semiconductor microcavity, and have shown that highly efficient two-photon excitation can be realized by utilizing the photon pair, compared with conventional methods. In addition, we have shown that we can concurrently realize the selective excitation of an electronic state and the enhancement of excitation efficiency by controlling the quantum correlation of the photon pair.
