Coauthors	Hu, Liang; Poli, Nicola; Tino, Guglielmo M.
Abstract	The performance of traditional long-baseline atom interferometry for sensitive gravity measurements is limited by the phase noise requirements of the laser source used to interrogate the atomic ensemble. The instrument sensitivity can be significantly enhanced, in the measurement of the gravity difference between two distant locations, by operating the interferometer on a single-photon transition such as the strontium optical clock transition. This scheme features the advantage that the photon phase is set at the emission from the laser source and does not acquire extra noise in the path between the two atomic accelerometers. Such a device can find scientifically interesting applications in the field of low-frequency gravitational wave detection and in tests of the equivalence principle at the quantum level. In this talk I will illustrate the main achievements attained in our group in the implementation of an interferometer operating on a single-photon transition [PRL 119, 263601 (2017)].
