- For example, one could perform quantum cryptography with an entangled photon pair or an entangled pair of atomic nuclei or even a photon and a nucleus entangled together. 例如，我们可以用一对缠结光子，也可以用一对缠结原子核，甚至是缠结在一起的一个光子与一个原子核，来执行量子密码学的工作。
- It is using stratospheric platform and geosynchronous satellite as quantum repeater to deliver entangled photon pairs. 该系统以平流层平台和地球同步卫星为量子中继站，分发纠缠光子对。
- Using satellites to deliver single photon or entangled photon pairs is a unique solution to realize long-distance quantum communications networks. 利用卫星来分发单光子(或纠缠光子对)的方法为远程量子通信网络提供了一种独特的解决方案。
- I bought a pair of tan leather shoes the other day. 前几天我买了双棕褐色的皮鞋。
- Experimental results of four-photon de Broglie wavelength measurement are analyzed based on a local description for the quantum state and optical field of photon pairs generated from spontaneous parametric down-conversion(SPDC). 采用对自发参量下转换过程产生的光子对的量子态和光场的非纠缠态描述,分析了由自发参量下转换过程产生的四光子的德布罗意波长测量的实验,得到了与实验观测相一致的结果。
- A true analogy to the Hawking effect must meet an important condition: the virtual phonon pairs must begin life in their ground state, as do the virtual photon pairs around the black hole. 真正霍金效应的类比，必须要符合一个重要的条件：虚声子对必须从它们的基态中诞生，就像是黑洞附近的虚光子对一样。
- The researchers first created two entangled photon pairs, sent one photon from each pair through a beam splitter to entangle them, and then sent one of the remaining photons through a beam splitter with a fifth photon, thereby entangling all five photons. 研究人员先制造出两对缠结的光子，再将每对中的其中一个光子经由分光器形成缠结，再让两对中各自剩下的光子和第五个光子一起通过分光器，如此便使五个光子全部缠结在一起。
