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

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

Some aspects of the entangled states generated through an atom–field interaction through the Jaynes–Cummings model are discussed. The separability and inseparability of these states are studied for different parameters of the model concerning the field and the atom. We calculated the minimum amount of entanglement contained in the inseparable state and compared it with the total correlation through the mutual ... إقراء المزيد
