Entanglement in Graph States and its Applications
M. Hein, W. Dür, J. Eisert +3
Graph states form a rich class of entangled states that exhibit important aspects of multi-partite entanglement. At the same time, they can be described by a number of parameters t…
Standard forms of noisy quantum operations via depolarization
W. Dür, M. Hein, J. I. Cirac +1
We consider noisy, non-local unitary operations or interactions, i.e. the corresponding evolutions are described by completely positive maps or master equations of Lindblad form. W…
Entanglement properties of multipartite entangled states under the influence of decoherence
M. Hein, W. Dür, H. -J. Briegel
We investigate entanglement properties of multipartite states under the influence of decoherence. We show that the lifetime of (distillable) entanglement for GHZ-type superposition…
Entanglement in spin chains and lattices with long-range Ising-type interactions
W. Dür, L. Hartmann, M. Hein +2
We consider N initially disentangled spins, embedded in a ring or d-dimensional lattice of arbitrary geometry, which interact via some long--range Ising--type interaction. We inves…
Multi-party entanglement in graph states
M. Hein, J. Eisert, H. J. Briegel
Graph states are multi-particle entangled states that correspond to mathematical graphs, where the vertices of the graph take the role of quantum spin systems and edges represent I…
Local invariants for multi-partite entangled states allowing for a simple entanglement criterion
Hans Aschauer, John Calsamiglia, Marc Hein +1
We present local invariants of multi-partite pure or mixed states, which can be easily calculated and have a straight-forward physical meaning. As an application, we derive a new e…
