Parameter Calibration for Reduced-Bandwidth Two-Photon Waveguide-QED Simulations
Romain Piron, Akihito Soeda
Waveguide-QED platforms represent one potential approach to scalable quantum technologies, but their simulation remains computationally demanding due to the large number of frequen…

Renormalization Treatment of IR and UV Cutoffs in Waveguide QED and Implications to Numerical Model Simulation
Romain Piron, Akihito Soeda
We present a non-perturbative, first-principles derivation of renormalization relations for waveguide-QED models, explicitly accounting for the infrared (IR) and ultraviolet (UV) c…

Quantum Annealing for Active User Detection in NOMA Systems
Romain Piron, Claire Goursaud
Detecting active users in a non-orthogonal multiple access (NOMA) network poses a significant challenge for 5G/6G applications. Traditional algorithms tackling this task, relying o…
