Abstract
It is discussed how systems of quantum-correlated (entangled)particles or atoms behave in external gravitational fields and what gravitational effects may exist in such systems. An experimental setup is proposed which improves the sensitivity of the Ramsey interferometer by the usage of quantum-correlated atoms. Entanglement of atoms improves the sensitivity to small phase shifts in times. This scheme may be used for observing gravity-induced phase shifts in laboratory.
