A Photon Is Emitted and Reabsorbed by An Artificial Atom

Caption

A microscopic cavity of two highly reflective mirrors is used to allow an enclosed artificial atom (known as a quantum dot) to interact with a single photon. A photon is emitted and reabsorbed up to 10 times by the quantum dot before it is lost. The quantum dot is electrically controlled within a semiconductor chip.
