A quantum light emitting diode for the standard telecom wavelength around 1550 nm

TREL shows in Nature Communications that quantum dot devices based on indium phosphide are capable of electrically injected single photon and entangled photon pair emission around 1550 nm. Entanglement fidelity of 87 ± 4% is sufficient for the application of one-way error correction protocols and the emission at 1550 nm can be directly integrated with existing long distance quantum communication and cryptography systems.

Experimental measurement device independent quantum digital signatures

Proof-of-principle demonstration of quantum digital signatures (QDS) mediated by measurement-device-independent quantum key distribution (MDI-QKD). Published today in Nature Communications TREL has devised an efficient protocol to distil multiple signatures from the same block of data, thus reducing the statistical fluctuations in the sample and greatly enhancing the final QDS rate in the finite-size scenario.
