Self-organization of atoms in a cavity field: threshold, bistability and scaling laws
J. K. Asboth, P. Domokos, H. Ritsch +1
We present a detailed study of the spatial self-organization of laser-driven atoms in an optical cavity, an effect predicted on the basis of numerical simulations [P. Domokos and H…
Spin gases as microscopic models for non-Markovian decoherence
L. Hartmann, J. Calsamiglia, W. Dür +1
We analyze a microscopic decoherence model in which the total system is described as a spin gas. A spin gas consists of N classically moving particles with additional, interacting…
A treatment of the quantum partial entropies in the atom-field interaction with a class of Schrodinger cat states
A. -S. F. Obada, H. A. Hessian, Mahmoud Abdel-Aty
This communication is an enquiry into the circumstances under which entropy and subentropy methods can give an answer to the question of quantum entanglement in the composite state…
Distillation of multipartite entanglement by complementary stabilizer measurements
Akimasa Miyake, Hans J. Briegel
We propose a scheme of multipartite entanglement distillation driven by a complementary pair of stabilizer measurements, to distill directly a wider range of states beyond the stab…
Fast simulation of stabilizer circuits using a graph state representation
Simon Anders, Hans J. Briegel
According to the Gottesman-Knill theorem, a class of quantum circuits, namely the so-called stabilizer circuits, can be simulated efficiently on a classical computer. We introduce…
Multipartite entanglement in spin chains
Otfried Guehne, Geza Toth, Hans J. Briegel
We investigate the presence of multipartite entanglement in macroscopic spin chains. We discuss the Heisenberg and the XY model and derive bounds on the internal energy for systems…
