Subsonic critical velocity at finite temperature
Patrick Navez, Robert Graham
Based on the dielectric formalism in the generalised random phase approximation, we generalise the description of a Bose condensed gas to allow for a relative velocity between the…

Cloning quantum entanglement in arbitrary dimensions
E. Karpov, P. Navez, N. J. Cerf
We have found a quantum cloning machine that optimally duplicates the entanglement of a pair of -dimensional quantum systems. It maximizes the entanglement of formation containe…

The optimal cloning of quantum coherent states is non-Gaussian
N. J. Cerf, O. Krueger, P. Navez +2
We consider the optimal cloning of quantum coherent states with single-clone and joint fidelity as figures of merit. Both optimal fidelities are attained for phase space translatio…
