PROJECT TITLE :

Deterministic generation of symmetric multi-qubit Dicke states: an application of quantum feedback control

ABSTRACT:

During this study, the authors explore a way to deterministically generate symmetric multi-qubit Dicke states like symmetric W-states, from arbitrary initial states in a very cavity quantum electrodynamics (QED) system with the help of measurement-primarily based quantum feedback control. The concrete implementation procedures of the feedback strategy, which is made in the form of only 2 constant modes, are presented in detail. Similarly, the feasibility of the management theme in getting ready symmetric multi-qubit Dicke states is explicitly demonstrated by theoretical studies and numerical simulations.
