Heralded entangled photons to enable quantum networking and computation

该项目旨在通过发展新的科学，即非破坏性验证的光子纠缠态，来推动量子网络和量子计算。尽管潜力巨大，但由于缺乏以光子纠缠态为形式的关键资源，光子量子技术一直受到阻碍。该项目的预期成果包括预告态产生的新实验能力和用于光子电路设计的强大的新理论方法。这应该能够实现具有真正优势的量子协议，这是迈向支撑下一代网络安全的实用量子技术的关键一步。

This project aims to advance quantum networking and quantum computation by developing the science of new heralded, i.e. nondestructively verified, entangled states of photons. Despite great potential, photonic quantum technologies have been held back by the lack of key resources in the form of heralded entangled states of photons. Expected outcomes of the project include novel experimental capabilities of heralded state generation and powerful new theoretical methods for photonic circuit design. This should enable the realisation of quantum protocols with a genuine advantage, a critical step towards practical quantum technologies underlying the next generation of cybersecurity.
