Optimal entanglement witnesses for continuous-variable systems
P. Hyllus, J. Eisert
This paper is concerned with all tests for continuous-variable entanglement that arise from linear combinations of second moments or variances of canonical coordinates, as they are…
Correlations, spectral gap, and entanglement in harmonic quantum systems on generic lattices
M. Cramer, J. Eisert
We investigate the relationship between the gap between the energy of the ground state and the first excited state and the decay of correlation functions in harmonic lattice system…
Half the entanglement in critical systems is distillable from a single specimen
R. Orus, J. I. Latorre, J. Eisert +1
We establish that the leading critical scaling of the single-copy entanglement is exactly one half of the entropy of entanglement of a block in critical infinite spin chains in a g…
Single-copy entanglement in critical spin chains
J. Eisert, M. Cramer
We introduce the single-copy entanglement as a quantity to assess quantum correlations in the ground state in quantum many-body systems. We show for a large class of models that al…
Optical generation of matter qubit graph states
S. C. Benjamin, J. Eisert, T. M. Stace
We present a scheme for rapidly entangling matter qubits in order to create graph states for one-way quantum computing. The qubits can be simple 3-level systems in separate cavitie…
Gaussian quantum channels
J. Eisert, M. M. Wolf
This article provides an elementary introduction to Gaussian channels and their capacities. We review results on the classical, quantum, and entanglement assisted capacities and di…
