Quantum key distribution (QKD) is already established as a physical approach to secure communications, which will continue to be secure in a future, fully-quantum-enabled world. However, there is growing interest in new quantum information protocols, which go beyond QKD, to provide quantum advantage in other scenarios, such as different data security situations, distributed quantum processing, and other useful quantum information tasks. This project will research and develop such new quantum information protocols, leveraging, for example, distributed entanglement and information, quantum measurements, relativistic constraints, and counterfactual techniques. There is also scope for modelling, to investigate protocol robustness under practical errors. There may also be potential for collaboration with experiment, for protocols that might be investigated or tested with current quantum technology hardware.

量子密钥分发（QKD）已经被确立为一种安全通信的物理方法，在未来完全量子化的世界中将继续保持安全。然而，人们对超越QKD的新量子信息协议越来越感兴趣，以在其他场景中提供量子优势，例如不同的数据安全情况，分布式量子处理和其他有用的量子信息任务。该项目将研究和开发这种新的量子信息协议，例如利用分布式纠缠和信息，量子测量，相对论约束和反事实技术。也有建模的范围，调查协议的鲁棒性下的实际错误。也可能有与实验合作的潜力，用于可能使用当前量子技术硬件进行研究或测试的协议。
