Abstract

We demonstrate that a quantum receiver can monitor the conditions of a communications channel simultaneously with data transmission, with no additional measurements required. The sensing scheme uses the confidence vector estimated by the state identification algorithm to monitor changes in power and phase noise and is demonstrated experimentally. To measure confidence, the output of the quantum receiver is processed using the Bayesian formula for each individual measurement. By optimizing the statistical analysis of confidence vector data we achieve 0.5% sensitivity to power fluctuations with no interruption of data transmission.
