Abstract
A model of a quantum network node based on a photonic molecule (PM) containing a quantum dot, which acts as a source and a router of single photons and correlated photon pairs, is proposed. Methods for coherent control of spatially entangled states of the node by local modification of its optical properties are studied. The fidelity of reproduction of these states and their generation time are calculated. The possibility of temperature tuning of an optical spectrum of triangular and square PMs consisting of four GaAs microdisks is shown. The dependence of eigenmode wavelengths on temperature and the distance between the microdisks are calculated.
