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…
Optimal conversion of non--local unitary operations
W. Dür, G. Vidal, J. I. Cirac
We study when a non--local unitary operation acting on two --level systems can probabilistically simulate another one when arbitrary local operations and classical communication…
Catalysis in non--local quantum operations
G. Vidal, J. I. Cirac
We show how entanglement can be used, without being consumed, to accomplish unitary operations that could not be performed with out it. When applied to infinitesimal transformation…
Optimal simulation of two-qubit Hamiltonians using general local operations
C. H. Bennett, J. I. Cirac, M. S. Leifer +4
We consider the simulation of the dynamics of one nonlocal Hamiltonian by another, allowing arbitrary local resources but no entanglement nor classical communication. We characteri…
Storing quantum dynamics in quantum states: stochastic programmable gate for U(1) operations
G. Vidal, L. Masanes, J. I. Cirac
We show how quantum dynamics can be captured in the state of a quantum system, in such a way that the system can be used to stochastically perform, at a later time, the stored tran…
Visible compression of commuting mixed states
W. Dür, G. Vidal, J. I. Cirac
We analyze the problem of quantum data compression of commuting density operators in the visible case. We show that the lower bound for the compression factor given by the Levitin-…
