Generating Spatially-Correlated Non-Classical Fields Using Two- and Three-Dimensional Quantum Antennas

The fields generated by two- and three-dimensional quantum antennas from identical independent two-level emitters are calculated and analyzed. It is shown that two- and three-dimensional quantum antennas can produce much better localization of the distribution of the emitted two- and three-photon field and its correlations than one-dimensional antennas. This means that two- and three-dimensional quantum antennas offer promise for quantum-radar applications.
