Entanglement and permutational symmetry
Geza Toth, Otfried Gühne
We study the separability of permutationally symmetric quantum states. We show that for bipartite symmetric systems most of the relevant entanglement criteria coincide. However, we…
Alkaline-Earth-Metal Atoms as Few-Qubit Quantum Registers
Alexey V. Gorshkov, Ana Maria Rey, Andrew J. Daley +4
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom a…
High fidelity entanglement of 43Ca+ hyperfine clock states
G. Kirchmair, J. Benhelm, F. Zähringer +3
In an experiment using the odd calcium isotope 43Ca+ we combine the merits of a high fidelity entangling operation on an optical transition (optical qubit) with the long coherence…
Entanglement detection
Otfried Gühne, Geza Toth
How can one prove that a given state is entangled? In this paper we review different methods that have been proposed for entanglement detection. We first explain the basic elements…
Atomic three-body loss as a dynamical three-body interaction
A. J. Daley, J. M. Taylor, S. Diehl +2
We discuss how large three-body loss of atoms in an optical lattice can give rise to effective hard-core three-body interactions. For bosons, in addition to the usual atomic superf…
First-Forbidden Continuum- and Bound-State beta^- -Decay Rates of Bare 205Hg80+ and 207Tl81+ Ions
M. Faber, A. N. Ivanov, P. Kienle +3
We calculate the decay rates lambda_(beta^-_c) and lambda_(beta^-_b) of the continuum- and bound-state beta^- decays for bare 205Hg80+ and 207Tl81+ ions. For the ratio of the decay…
