Platonic constellations of quantum polarization coherent states in Stokes space for photonic communications
摘要
We present an analysis of the detection of polarization coherent states with Stokes parameters modulation, in symmetrical 3-dimensional (3D) constellations, centered at the vertices of Platonic polyhedra, for applications in photonic communications, as a quantum extension of the classical M-ary polarization-shift-keying (M-aryPolSK) formats.
We evaluate the communications system performance, applying a quantum quasi-probability analysis on the Poincaré sphere, in the detection of the 3D received constellation; we compute the main performance measures: the symbol error probability and the mutual information, for the five Platonic constellations, as well as the trade-offs between their spectral and power efficiencies.
We compare the performance of these 3D Platonic polyhedra constellations of Stokes parameters, to those of the usual 1D and 2D polygonal modulations, in their applications in quantum photonic communications.
