The present paper is devoted to consider the problem of the interaction between a pair of entangled qubits and a multiphotons cavity mode. The deformed operators are involved in the Hamiltonian model which represents such system. The exact solution of the wave function is obtained and the density matrix is contracted. For two different types of Bell states, the purity ... إقراء المزيد

We report on the observation of new features in a superconducting charge qubit system. The system we analyze comprises of a single Cooper-pair box sequentially coupled to two microwave cavity fields. Simulations of the full qubit–field dynamics show significant total correlation and coherence loss. By suitably choosing the system’s parameters and precisely controlling the dynamics, we demonstrate the generation of ... إقراء المزيد
