Аннотация

В данном обзоре рассматриваются различные способы создания однофотонных источников (ИОФ). Задача генерации одиночных фотонов может решаться разными способами, и на текущий момент среди них нет такого, который был бы существенно предпочтителен.

В первой части обзора обсуждались требования к однофотонным источникам и критерии характеризации источников. В первую часть обзора вошли источники одиночных фотонов на основе одиночных ионов и на основе одиночных атомов.

Во второй части рассмотрены ИОФ на квантовых точках и на центрах окраски в кристаллах.
