我们已经建立了一个成像系统，它使用光子的位置或飞行时间信息来对对象成像，同时使用光子的偏振来确保安全。这种能力使我们能够获得一幅安全的图像，在攻击中，被成像的对象截获并重新发送带有修改信息的成像光子。通常被称为“干扰”，这种类型的攻击通常是针对雷达等主动成像系统。为了干扰我们的成像系统，物体必须扰乱成像光子的微妙量子状态，从而引入揭示其活动的统计误差。(C)2012年美国物理研究所。[http://dx.doi.org/10.1063/1.4770298]
We have built an imaging system that uses a photon's position or time-of-flight information to image an object, while using the photon's polarization for security. This ability allows us to obtain an image which is secure against an attack in which the object being imaged intercepts and resends the imaging photons with modified information. Popularly known as "jamming," this type of attack is commonly directed at active imaging systems such as radar. In order to jam our imaging system, the object must disturb the delicate quantum state of the imaging photons, thus introducing statistical errors that reveal its activity.
