Quantum photonics devices for quantum communications

“量子互联网”通常被认为是未来一代的网络，其中共享的量子信号可以实现高度安全的通信，与远程量子计算机和量子增强计量学的接口等应用。到目前为止，许多不同的物理系统被认为是量子信息。虽然哪种系统最适合领导量子信息革命尚未出现，但很明显光子将在量子设备之间的通信中发挥重要作用。本文所要研究的基于光子纠缠的量子信息系统与量子通信、量子隐形传态和量子计算以及量子纠缠的基本实验有关。

The “Quantum Internet” is often considered the future generation of networking, where the shared quantum signals enable applications such as highly secure communications, interfacing to remote quantum computers and quantum enhanced metrology. As of today, many different physical systems are considered for quantum information. While it has yet to emerge which system is best suited to lead the quantum information revolution, it is clear that photons will play an important role in the communication between quantum devices. The photonic­ based quantum information systems that I plan to study are relevant for quantum communication, quantum teleportation and quantum computing, and also fundamental quantum entanglement experiments.
