Abstract

AREVALO AGUILAR, L.M.  and  MOYA-CESSA, H.. Information swapping scheme in cavity QED. Rev. mex. fis. [online]. 2003, vol.49, n.4, pp.307-309. ISSN 0035-001X.

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.
