Renormalization group transformations on quantum states
F. Verstraete, J. I. Cirac, J. I. Latorre +2
We construct a general renormalization group transformation on quantum states, independent of any Hamiltonian dynamics of the system. We illustrate this procedure for translational…
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…
Quantum benchmark for storage and transmission of coherent states
K. Hammerer, M. M. Wolf, E. S. Polzik +1
We consider the storage and transmission of a Gaussian distributed set of coherent states of continuous variable systems. We prove a limit on the average fidelity achievable when t…
Multiplicativity of maximal output purities of Gaussian channels under Gaussian inputs
A. Serafini, J. Eisert, M. M. Wolf
We address the question of the multiplicativity of the maximal p-norm output purities of bosonic Gaussian channels under Gaussian inputs. We focus on general Gaussian channels resu…
