Abstract
We theoretically study the control of a weak quantum light in a resonant three-level condensed medium derived by a pair of resonant counterpropagating laser fields. We analytically demonstrate that the adiabatic switching on of one of the control fields generates an entangled state of photon wave packets moving together at subnormal slow velocity in the medium with relative amplitudes determined by the control laser fields. An abrupt switching-off the control field makes the entangled wave packets propagate in the opposite direction with temporally reversed profiles relative to each other. We have analyzed the quantum control of the entanglement generation in terms of the adiabatic and nonadiabatic switching operations of the coupling laser pulse.
