In this letter we present a scheme for generating maximally entangled states of two cavity modes which enables us to generate complete set of Bell basis states having rather simple initial state preparation. Furthermore, we study the interaction of a two-level atom with two modes of electromagnetic field in a high Q cavity. The two-level atom acts as a control ... إقراء المزيد

In this contribution a nonlinear type of the correlated two-mode states (nonlinear pair-coherent states (NLPCS)) is introduced. Based on the resonant ion–cavity interaction, we propose a scheme to generate these states revealing their connection with the pair-coherent state (PCS) and investigate their nonclassical properties. The practical feasibility of this method is also discussed. The _s_-parameterized characteristic function (CF) of the ... إقراء المزيد

We discuss a mechanism for generating a maximum entangled state (Greenberger–Horne–Zeilinger (GHZ)) in a coupled quantum dots system, based on analytical techniques. The reliable generation of such states is crucial for implementing solid-state based quantum information schemes. The signature originates from a remarkably weak field pulse or a far off-resonance effects which could be implemented using technology that is currently ... إقراء المزيد
