Introduction to the basics of entanglement theory in continuous-variable systems
J. Eisert, M. B. Plenio
We outline the basic questions that are being studied in the theory of entanglement. Following a brief review of some of the main achievements of entanglement theory for finite-dim…
Towards mechanical entanglement in nano-electromechanical devices
J. Eisert, M. B. Plenio, S. Bose +1
We study arrays of mechanical oscillators in the quantum domain and demonstrate how the motions of distant oscillators can be entangled without the need for control of individual o…
Exact decoherence to pointer states in free open quantum systems is universal
J. Eisert
In this paper it is shown that exact decoherence to minimal uncertainty Gaussian pointer states is generic for free quantum particles coupled to a heat bath. More specifically, the…
Inhomogeneous atomic Bose-Fermi mixtures in cubic lattices
M. Cramer, J. Eisert, F. Illuminati
We determine the ground state properties of inhomogeneous mixtures of bosons and fermions in cubic lattices by studying the Bose-Fermi Hubbard model including parabolic confining p…
Multi-party entanglement in graph states
M. Hein, J. Eisert, H. J. Briegel
Graph states are multi-particle entangled states that correspond to mathematical graphs, where the vertices of the graph take the role of quantum spin systems and edges represent I…
Distillation of continuous-variable entanglement with optical means
J. Eisert, D. E. Browne, S. Scheel +1
We present an event-ready procedure that is capable of distilling Gaussian two-mode entangled states from a supply of weakly entangled states that have become mixed in a decoherenc…
Mixtures of Bosonic and Fermionic Atoms in Optical Lattices
Alexander Albus, Fabrizio Illuminati, Jens Eisert
We discuss the theory of mixtures of Bosonic and Fermionic atoms in periodic potentials at zero temperature. We derive a general Bose--Fermi Hubbard Hamiltonian in a one--dimension…
Entanglement transformations of pure Gaussian states
G. Giedke, J. Eisert, J. I. Cirac +1
We present a theory of entanglement transformations of Gaussian pure states with local Gaussian operations and classical communication. This is the experimentally accessible set of…
