Summary:
In the efforts to apply quantum communication to atmospheric channels and on an intercontinental scale, a diverse range of inherent effects in the quantum channel have been attracting research attention in recent years. Beam wandering is an inherent effect that is known to occur when wireless communication methods such as satellite-based global communications are considered, and a previous study on these terms provides a good example of non-Gaussian noise. In our study, we present and consider the error performances for optimum quantum measurement, suboptimal measurement, and optimum classical measurement approaches using an $M$-ary phase-shift keying modulation scheme when beam wandering occurs.
