When atom interacts with non-resonant light,the clock frequency is slightly modified by thelight shift effect (Cohen-Tannoudji, 1961)Non-resonant atom experienceslight-shifts proportional to thephoton number N, with oppositesigns in levels e and gegThe shifts result in a phase shift ofthe atomic dipole when atomcrosses the cavity:!"(N) = N# 0# 0 : phase shift per photoncan be as large as $0 photon 1 photonMeasuring !" amounts to a QND photon counting
