Entanglement generation and Hamiltonian simulation in Continuous-Variable Systems
Barbara Kraus, Klemens Hammerer, Geza Giedke +1
Several recent experiments have demonstrated the promise of atomic ensembles for quantum teleportation and quantum memory. In these cases the collective internal state of the atoms…

Characterization of non-local gates
K. Hammerer, G. Vidal, J. I. Cirac
A non-local unitary transformation of two qubits occurs when some Hamiltonian interaction couples them. Here we characterize the amount, as measured by time, of interaction require…

Interaction cost of non-local gates
G. Vidal, K. Hammerer, J. I. Cirac
We introduce the interaction cost of a non-local gate as the minimal time of interaction required to perform the gate when assisting the process with fast local unitaries. This cos…
