Experimental and theoretical challenges for the trapped electron quantum computer

I. Marzoli, P. Tombesi, G. Ciaramicoli +11

We discuss quantum information processing with trapped electrons. After recalling the operation principle of planar Penning traps we sketch the experimental conditions to load, coo…

Most quantum states are too entangled to be useful as computational resources

D. Gross, S. Flammia, J. Eisert

It is often argued that entanglement is at the root of the speedup for quantum compared to classical computation, and that one needs a sufficient amount of entanglement for this sp…

Quantum computational webs

D. Gross, J. Eisert

We introduce the notion of quantum computational webs: These are quantum states universal for measurement-based computation which can be built up from a collection of simple primit…

A perturbative approach to inelastic collisions in a Bose-Einstein Condensate

R. B. Mann, M. B. Young, I. Fuentes-Schuller

It has recently been discovered that for certain rates of mode-exchange collisions analytic solutions can be found for a Hamiltonian describing the two-mode Bose-Einstein condensat…

Information propagation through quantum chains with fluctuating disorder

Christian K. Burrell, Jens Eisert, Tobias J. Osborne

We investigate the propagation of information through one-dimensional quantum chains in fluctuating external fields. We find that information propagation is suppressed, but in a qu…

Quantum fluctuations in the image of a Bose gas

Antonio Negretti, Carsten Henkel, Klaus Molmer

We analyze the information content of density profiles for an ultracold Bose gas of atoms and extract resolution limits for observables contained in these images. Our starting poin…

Superconducting atom chips: advantages and challenges

Valery Dikovsky, Vladimir Sokolovsky, Bo Zhang +2

Superconductors are considered in view of applications to atom chip devices. The main features of magnetic traps based on superconducting wires in the Meissner and mixed states are…

Area laws for the entanglement entropy - a review

J. Eisert, M. Cramer, M. B. Plenio

Physical interactions in quantum many-body systems are typically local: Individual constituents interact mainly with their few nearest neighbors. This locality of interactions is i…

Supersonic quantum communication

J. Eisert, D. Gross

When locally exciting a quantum lattice model, the excitation will propagate through the lattice. The effect is responsible for a wealth of non-equilibrium phenomena, and has been…

A random matrix theory of decoherence

T. Gorin, C. Pineda, H. Kohler +1

Random matrix theory is used to represent generic loss of coherence of a fixed central system coupled to a quantum-chaotic environment, represented by a random matrix ensemble, via…

Thermodynamical Control by Frequent Quantum Measurements

Noam Erez, Goren Gordon, Mathias Nest +1

Heat flow between a large ``bath'' and a smaller system brings them progressively closer to thermal equilibrium while increasing their entropy. Deviations from this trend are fluct…

Multi-mode bosonic Gaussian channels

F. Caruso, J. Eisert, V. Giovannetti +1

A complete analysis of multi-mode bosonic Gaussian channels is proposed. We clarify the structure of unitary dilations of general Gaussian channels involving any number of bosonic…

Enhanced phase sensitivity and soliton formation in an integrated BEC interferometer

Antonio Negretti, Carsten Henkel

We study the dynamics of Bose-Einstein condensates in time-dependent microtraps for the purpose of understanding the influence of the mean field interaction on the performance of i…
