Atomic vapour microcells

Tubes for quantum electronics

Nature Photonics volume 4, pages 74–75 (2010)Cite this article

Subjects

Micrometre-sized atomic vapour cells hosting robust entangled atomic states at room temperature offer a promising route to the realization of quantum photonic devices such as quantum gates and single-photon sources.

Similar to how the invention of the vacuum tube triggered the age of wireless information, radio and television, we may now be witnessing a similarly critical moment in the development of quantum electronics. This is due to a recent successful experiment by researchers from the University of Stuttgart in Germany and the University of Oklahoma in the USA.
