Квантовый транспорт единичного фотона через субволновое отверстие единичным атомом
The localization and transport of a photon through a subwavelength hole with the help of a neutral atom are studied. A method proposed and realized in the study is based on the absorption of a photon by a neutral atom directly in front of a subwavelength hole, the flight of the atom through the hole, and photon emission on the other side of the screen. The influence of the interaction of the excited atom flying through the subwavelength channel with the screen material is estimated. The estimate showed that the atomic exci- tation can be quenched in holes with diameters smaller than 200 nm, which affects the photon transport effi- ciency.
