The Sheffield team with the National Epitaxy Facility will demonstrate entangled LEDs emitting at the commercially important fibre wavelength of 1550nm. Building on work in two previous IUK projects, the team will develop new LED structures that optimise single photon light extraction and allow the LEDs to be demonstrated in a GHz clocked high fidelity quantum network. The complete system will be demonstrated with our industrial partners Toshiba and BT Labs and will provide a major step forward in demonstrating the feasibility of solid-state entangled LED systems for high fidelity Quantum Key Distribution (QKD) fibre networks and the overall development of quantum communications technologies.

谢菲尔德团队与国家外延设施将展示以商业上重要的光纤波长 1550nm 发光的纠缠 LED。在之前两个 IUK 项目的基础上，该团队将开发新的 LED 结构，优化单光子光提取，并允许 LED 在 GHz 时钟高保真量子网络中进行演示。完整的系统将与我们的工业合作伙伴东芝和英国电信实验室一起进行演示，并将在展示用于高保真量子密钥分配 (QKD) 光纤网络的固态纠缠 LED 系统的可行性以及量子通信的整体发展方面迈出重要一步技术。
