Robust Synchronization With Uniform Ultimate Bound Between Two Different Chaotic Systems With Uncertainties

“…[21][22][23][24][25][26] While the chaotic system is perturbed by random or regular noise, synchronization issue is studied. [27][28][29][30][31] Adaptive control is one of the most efficient methods to deal with these problems with uncertainties.…”

Simple schemes for generating the three-atom W state and the Greenberger–Horne–Zeilinger state among nonidentical atoms

“…It is well known that entanglement not only can be used to study the nonlocal and nonclassical characteristics of quantum particles 3 , but also has extensive applications in quantum information precessing, such as quantum key distribution [1], quantum teleportation [2], quantum error correction [3] and entanglement purification [4]. Therefore, the preparation of various entangled states [5][6][7][8][9][10] has become an important technique in quantum information processing. Dür et al [11] have shown that there are two inequivalent tripartite entangled states, namely the Greenberger-Horne-Zeilinger (GHZ) state and the W state, one of which cannot be converted to the other under stochastic local operations and classical communication.…”

“…Then we let atom 3, initially prepared in |g 3 , go through the cavity and the transition |e 3 → |g 3 is coupled to the right circularly polarizing cavity mode. The Hamiltonian describing the interaction between atom 3 and the left circularly polarizing cavity mode is the same as equation (7).…”
