Abstract

I introduce the recent advancements of single atom physics and technology in silicon devices. Single atom-based devices display a rich variety of physical phenomena ranging from quantum transport to control of single electrons, to Kondo effect and single photon emission. I review technological issues and future prospects in the field of quantum computing and quantum communications, including the most recent research of room temperature single photon regime from Er emission.
