Taking place at the forefront of current research, the goal of this project is to use semiconductor quantum dots with emission in the telecom wavelength range to generate multiphoton entangled states. This is a complex challenge, relying on answering many interesting research questions along the way. These questions range from the fundamental, such as 'what are the quantum properties of the quantum dot spin states?' and 'How can we harness these for the efficient generation of multiphoton states?' to the applied: 'Given the quantum dot characteristics and limitations such as coherence times, what are the best methods and protocols to apply?' and 'In practice, how can we enhance quantum data transfer beyond the current limits using these novel states?' Finally, there is even the potential to put the multiphoton states to good use in a real-world test of quantum data transmission over a fibre network.

该项目的目的是在当前研究的最前沿，是使用在电信波长范围内发射的半导体量子点来生成多霍顿纠缠状态。这是一个复杂的挑战，依靠在此过程中回答许多有趣的研究问题。这些问题范围从基本问题，例如“量子点旋转状态的量子特性是什么？”和“我们如何利用这些利用这些多人国家的有效产生？”对所应用的：“鉴于量子点的特性和限制（例如相干时间），应用哪些最佳方法和协议是什么？”在实践中，我们如何使用这些新型状态来增强量子数据传输超出当前限制？”最后，甚至有潜力将多光子状态在光纤网络上的量子数据传输的真实世界测试中充分利用。
