The project aims to tackle some of the pressing challenges in quantum communication by integrating CNOT gates within entanglement-based wavelength-division-multiplexed quantum key distribution (WDM-QKD) networks. This will be achieved through silicon photonic chips as they offer scalable, integrable and efficient platforms for these operations, particularly focusing on demonstrating low-loss, high fidelity and high performance. The experiment will involve the generation and distribution of bi-partite entangled states to quantum end nodes, using wavelength multiplexing to form a fully connected network amongst all users. The operation of CNOT gates on those entangled states will facilitate communication between several quantum computers, therefore bridging the current gap between quantum communication and computation, and advancing us towards the realisation of a fully deployable quantum internet.

该项目旨在通过将 CNOT 门集成到基于纠缠的波分复用量子密钥分发 (WDM-QKD) 网络中来解决量子通信中的一些紧迫挑战。这将通过硅光子芯片来实现，因为它们为这些操作提供可扩展、可集成和高效的平台，特别注重展示低损耗、高保真度和高性能。该实验将涉及生成二分纠缠态并将其分发到量子终端节点，使用波长复用在所有用户之间形成完全连接的网络。 CNOT 门对这些纠缠态的操作将促进多个量子计算机之间的通信，从而弥合当前量子通信和计算之间的差距，并推动我们实现完全可部署的量子互联网。
