项目摘要

Quantum entanglement sources are to quantum technology what lasers are to optical technology. The invention of lasers hascreated a photonics industry worth of $650 billion in 50 years, with applications cover everything from DVD players to industrialcutting and welding, from laser surgery to long-distance communication. The Internet would not have been possible without lasers.Likewise, entangled photon sources will play an equally important role in not-too-distant future. They produce photons exhibitingquantum correlations that cannot be mimicked by classical particles. The quantum correlations can be harnessed to performfunctions impossible to achieve classically, such as unconditional security in communication, efficient algorithm in quantumcomputing, and ultra-high resolution in quantum imaging.A basic quantum entanglement source produces entangled photon pairs, which are pairs of photons prepared in a specialquantum state that exhibits strong correlations. Such correlations enable many unconventional usages of the quantum resource.Entanglement-based quantum key distribution (QKD), for example, utilizes the correlation of the photons sent to two remoteparties and allows them to share a common cryptographic key and any eavesdropping attempt would result in a detectabledeterioration of correlation.The aim of this project is to develop a practical, low-cost, turn-key entangled photon source based entirely on fiber-compatiblecomponents. We will leverage Ozs expertise in photonic packaging and product development. Quantum technology will play animportant role in the 21st century. Entanglement sources are essential for many quantum applications. This proposal aims to takethe first step towards developing commercially viable entanglement sources.

量子纠缠来源是量子技术，激光器对光学技术是什么。激光的发明在50年内创造了一个价值6500亿美元的光子行业，其应用程序涵盖了从DVD播放器到工业切割和焊接的所有内容，从激光手术到长距离通信。没有激光器，互联网将是不可能的。与此同时，纠缠的光子源将在不远处的未来中发挥同样重要的作用。它们产生表现出无法通过经典颗粒模仿的光子。可以利用量子相关性，以执行不可能实现的实现，例如沟通中的无条件安全性，量子计算中的有效算法以及量子成像中的超高分辨率。基本的量子纠缠源可产生纠缠的光子对，这些光子对在特种状态中制备的光子成对，该状态是强度较强的Correlations。例如，这种相关性使量子资源的许多非常规的用法。在纤维 - 棋子板上。我们将利用光子包装和产品开发方面的OZS专业知识。量子技术将在21世纪发挥动画作用。纠缠来源对于许多量子应用至关重要。该提案旨在朝着开发商业上可行的纠缠来源的第一步。
