Entangled multiphoton state generation with semiconductor quantum dots

该项目处于当前研究的前沿，其目标是利用在电信波长范围内发射的半导体量子点来产生多光子纠缠态。这是一个复杂的挑战，依赖于沿途回答许多有趣的研究问题。这些问题从最基本的，比如“量子点自旋态的量子特性是什么？”和“我们如何利用这些来有效地产生多光子态？”：“考虑到量子点的特性和限制，比如相干时间，最好的方法和协议是什么？”和“在实践中，我们如何使用这些新状态来增强量子数据传输，超越当前的限制？”最后，甚至有可能将多光子态用于光纤网络上量子数据传输的实际测试中。

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.
