Description

We propose a quantum interface which applies multiple passes of a pulse of light through an atomic sample with phase/polarization rotations in between the passes. Our proposal does not require nonclassical light input or measurements on the system, and it predicts rapidly growing entanglement of light and atoms from just coherent inputs. The proposed interface makes it possible to achieve a number of tasks within quantum-information processing, including teleportation between light and atoms, quantum memory for light, and squeezing of atomic and light variables
