arXiv:2606.25196v1 Announce Sort: cross
Summary: Reaching each reconfigurability and steady output indicators is a vital problem within the improvement of built-in photonic circuits for large-scale optical quantum data processing. This has led to the creation of multimode photonic processors, often known as reconfigurable multimode interferometers, which have wide-ranging functions in quantum and classical data processing. Nevertheless, sustaining part stability in multi-port enter indicators stays a major hurdle, significantly because of the part instabilities launched by lively cooling methods and temperature drifts within the photonic processor. On this examine, we suggest theoretical fashions to simulate part instability in photonic processors and validate them towards experimental outcomes. Two distinct modeling approaches have been employed: a Brownian random stroll and part reconstruction primarily based on experimentally noticed oscillating harmonics. Moreover, we verified and utilized our mannequin to a particular utility for enter part correction utilizing self-feedback management inside the photonic processor.
