Information swapping scheme in cavity QED

L.M. Arévalo Aguilar, H. Mo, a-Cessa.

Abstract


We present a method to swap information between atomic states by manipulating the interaction time between a quantum cavity field and two two-level atoms. We show that quantum information carried by one atom can be written onto a 'blank' state of the second atom, and the information contained in atom one is completely erased.

Keywords


Quantum information swapping; teleportation; 2-level atoms interacting with light
