Natural van der Waals silicates as hosts for telecom quantum emitters: the case of erbium-doped talc

Gellért Dolecsek, Zsolt Benedek, Nguyen Tien Son +1

Erbium ion is among the most promising solid-state single photon emitters and spin-photon interfaces for quantum networks, emitting directly in the telecom C-band in many host semi…
