Asymmetric Dicke Class States: Generation and Applications

Abstract:

Dicke class states are maximally entangled states of atoms or atom-like two-state entities involving a small number of excitations (much less that the total number of atoms). The so-called asymmetric Dicke states, which carry different relative phases for different permutations corresponding to different atomic entity being in the excited state, are more useful for quantum information processing tasks than the symmetric Dicke states. I have devised a practical conceptual proposal for generation of asymmetric Dicke states based on an existing proposal to generate symmetric Dicke states. I also show that the asymmetric Dicke-class states can be used for perfect teleportation and dense coding.
