Free‐Space Time‐Bin Encoded Quantum Key Distribution from Near‐ to Mid‐Infrared Wavelengths

Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.
This work investigates free‐space communication based on quantum key distribution (QKD) in the mid‐infrared. Time‐bin encoded QKD is simulated, and it is demonstrated that a free‐space QKD link operating in the mid‐infrared outperforms configurations based on conventional near‐infrared wavelengths under various weather scenarios, with a particular ...

Tunable Coupler–Augmented Microrings: Reconfigurable Q‐Factor Control for Foundry‐Scale Quantum Light Sources

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
Scalable quantum photonics require robust realization of quantum light sources for foundry‐scale fabrication. An interferometrically coupled silicon nitride microring resonator enables post‐fabrication control of bus–ring coupling. Thermal phase shifters adjust the Q‐factor and the pair generation rate, revealing that optimal generation does not occur ...
