An efficient numerical method for calculating the entanglement of formation of arbitrary mixed quantum states of any dimension
J. R. Gittings, A. J. Fisher
We present a conjugate gradient method for calculating the entanglement of formation of arbitrary mixed quantum states of any dimension and with any bipartite division of the Hilbe…

Lower limit on decoherence introduced by entangling two spatially-separated qubits
A. J. Fisher
It is shown that a generalization of the fluctuation-dissipation theorem places an upper bound on the figure of merit for any quantum gate designed to entangle spatially-separated…

Hybrid Luttinger liquid/Fermi liquid behaviour in an atomic wire on a surface
L. K. Dash, A. J. Fisher
Recent advances in single atom manipulation have made it possible to create "wires" in the form of atomic scale linear structures on a semiconductor surface. If such structures are…
