An Alternative Scheme to Generate Arbitrary Anticorrelated States of a Two-Mode Field via A-type Atom Resonant Interaction with a Two-Mode Cavity Field

摘要

An alternative scheme is presented to generate arbitrary anticorrelated states of a two-mode field.In the scheme,a sequence of A-type three-level atoms are orderly sent across the cavity to interact with the cavity field initially in the two-mode vacuum state.The detection of all the atoms in the ground state collapses the two-mode field to the desired state.In this way,we can prepare the anticorrelated states of a two-mode field.
