Nature Physics/ News and Views - Quantum optics: Coherence from spontaneity

Workgroup Arndt Group

04. May 2011  — Markus Arndt reports in the latest issue of Nature Physics on coherence from spontaneity in the field of Quantum optics.


The observation of quantum phenomena usually requires utmost control and isolation of a quantum system from its noisy environment. A study now shows how even a spontaneously emitted photon may force an atom into a coherent quantum state.
