Decoherence remains a major challenge in quantum computing hardware, and a variety of
physical-layer controls provide opportunities to mitigate the impact of this phenomenon …

An adaptive polarization controller (APC) is crucial in mitigating carrier fading in a self-
homodyne coherent detection (SHCD) system. In this paper, we propose a simplified APC …

A self-homodyne coherent (SHC) transmission system that has a good prospect in terms of
short-reach interconnections can simplify digital signal processing (DSP) and reduce the …

We present a complete optoelectronic unit for polarization visualization, switching and
control. The system is based on an FPGA unit and comprises: an acquisition unit containing …

Decoherence remains a major challenge in Near term, Intermediate scale Noisy Quantum
(NISQ) computers. This thesis proposes techniques for characterizing classical noise …

Optical fibers constitute a staggering portion of the physical layer underlying modern
communication networks. To extend the reach of such networks around the globe, long-haul …
