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 ...

A Zero‐Added‐Loss Multiplexing (ZALM) Source Simulation

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
This work presents a modular simulator for the Zero‐Added‐Loss Multiplexing (ZALM) architecture. It models the complete pipeline from SPDC sources through DWDM spectral filtering to the heralding station. By translating physical layer physics into system‐level metrics, the tool enables researchers to map fidelity‐rate trade‐offs and co‐design optical ...
