We present a heralded single-photon source with a much lower level of unwanted background photons in the output channel by using the herald photon to control a shutter in the heralded channel. The shutter is implemented using a simple field programable gate array controlled optical switch.
我们展示了一种通过利用预示光子来控制预示通道中的快门，从而在输出通道中具有低得多的不需要的背景光子水平的预示单光子源。该快门是使用简单的现场可编程门阵列控制的光开关来实现的。
