Graph states as ground states of many-body spin-1/2 Hamiltonians
M. Van den Nest, K. Luttmer, W. Dür +1
We consider the problem whether graph states can be ground states of local interaction Hamiltonians. For Hamiltonians acting on n qubits that involve at most two-body interactions,…

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…

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…
