We are developing atomic interferometry based on optical clock transition (see vacuum setup on the figure). In contrast with more commune atomic interferometer based on two photons Raman transition; our interferometer involves only one optical photon with an energy difference of six order of magnitude larger. The potential applications of this new type of interferometry are:

  • Combining ultraprecise time measurement with local gravity measurement
  • Test of general relativity using quantum coherence
  • Long baseline gradiometer for gravitational wave detection and search of dark matter.
