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…
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…
Entanglement and decoherence in spin gases
J. Calsamiglia, L. Hartmann, W. Dür +1
We study the dynamics of entanglement in spin gases. A spin gas consists of a (large) number of interacting particles whose random motion is described classically while their inter…
Algorithmic complexity of quantum states
C. Mora, H. J. Briegel
In this paper we give a definition for the Kolmogorov complexity of a pure quantum state. In classical information theory the algorithmic complexity of a string is a measure of the…
