Quantum filtering theory and the reduction of optical noises in optical detectors
Armien John Samson · 2016
In developing sensitive optical sensors, issues associated with optical crosstalk, dark count, and dark current persist. While designs have been created to mitigate the effects of these optical noises on the performance of the sensors, they are never fully addressed. This is mainly due to the highly probabilistic nature of the interaction of light and matter. This paper theoretically explores possible solutions that could lead to the significant reduction of these optical noises by presenting the problem in both the Markovian and Bayesian quantum feedback schemes and identifying the parameters that can be controlled and/or regulated. This paper then attempts to translate the quantum processes into realizable materials and/or systems suitable for fabrication or integration to existing system.
