First, we show how a single 2D layer can realize an efficient quantum memory, with an efficiency versus atom number that scales significantly better than is possible for a conventional ensemble. We also discuss how atomic Rydberg interactions can be used to endow the system with strong optical nonlinearities at the single-photon level. This can be used to realize an efficient photon-photon quantum gate, or to observe interesting phenomenology such as a "quantum aperture", where diffraction patterns emerge not in intensity measurements, but in higher-order quantum correlations.
