Enhancing Atom Interferomety by Entanglement

Enhancing Atom Interferometry by Entanglement

The fundamental limit in atom interferometers is the shot noise imposed by the number of atoms in each cycle. Overcoming this limit implies a improvement in the sensitivity, complementary to other activities targetting an increase of the scale factor. Various different approaches to sub shot noise detection were reported in the literature, but the transfer of these concepts to an inertially sensitive atom interferometer is non trivial. Together with the Atom Optics Group of C. Klempt we investigate how and which atom interferometers can actually benefit from entanglement.

Research Goals

  • Entanglement of momentum states
  • Application in an inertially sensitive atom interferometer
