We investigate multiparticle entanglement purification schemes which allow\none to purify all two colorable graph states, a class of states which includes\ne.g. cluster states, ...
We introduce a variational method for the approximation of ground states of strongly interacting spin systems in arbitrary geometries and spatial dimensions. The approach is bas...
In quantum communication via noisy channels, the error probability scales exponentially with the length of the channel. We present a scheme of a quantum repeater that overcomes ...
