标题： Shaping single photons and biphotons by inherent losses

摘要： 在单光子或双光子的产生过程中，不可避免地会存在本征损耗，但有趣的是，它为操控光子波包提供了机会。本文展示了如何利用参数下转换中的本征损耗来调整单光子和双光子的波包。作为例子，我们提出了一种利用本征损耗来实现单个周期内单光子的方法。我们的工作在量子通信、量子计算以及量子界面领域具有潜在应用价值。 显示英文摘要

摘要： Inherent loss is always to be avoided in generating single photons or biphotons, but interestingly it provides opportunities for manipulating the photon wave packet. In this paper we show how inherent loss in parametric down-conversion can be employed to tailor the wave packets of single photons and biphotons. As an example, we propose a scheme to realize a single photon in a single cycle using inherent loss. Our work has potential applications in quantum communication, quantum computation, and quantum interface.
