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…
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…
