Summary on Grant Application Form
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.
