An artificial Rb atom in a semiconductor with lifetime-limited linewidth
Jan-Philipp Jahn, Mathieu Munsch, Lucas Béguin +10
We report results important for the creation of a best-of-both-worlds quantum hybrid system consisting of a solid-state source of single photons and an atomic ensemble as quantum m…
Strain-tunable entangled-light-emitting diodes with high yield and fast operation speed
Jiaxiang Zhang, Johannes S. Wildmann, Fei Ding +6
Triggered sources of entangled photons play crucial roles in almost any existing protocol of quantum information science. The possibility to generate these non-classical states of…
