Multi-mode mediated exchange coupling in cavity QED

S. Filipp, M. Göppl, J. M. Fink +4

Microwave cavities with high quality factors enable coherent coupling of distant quantum systems. Virtual photons lead to a transverse exchange interaction between qubits, when the…

A quasipolynomial-time algorithm for the quantum separability problem

Fernando G. S. L. Brandao, Matthias Christandl, Jon Yard

We present a quasipolynomial-time algorithm for solving the weak membership problem for the convex set of separable, i.e. non-entangled, bipartite density matrices. The algorithm d…

Probing the negative Wigner function of a pulsed single photon point by point

Kaisa Laiho, Katiuscia N. Cassemiro, David Gross +1

We investigate quantum properties of pulsed light fields point by point in phase space. We probe the negative region of the Wigner function of a single photon generated by the mean…

Fabrication and heating rate study of microscopic surface electrode ion traps

N. Daniilidis, S. Narayanan, S. A. Möller +7

We report heating rate measurements in a microfabricated gold-on-sapphire surface electrode ion trap with trapping height of approximately 240 micron. Using the Doppler recooling m…

Tight bounds for classical and quantum coin flipping

Esther Hänggi, Jürg Wullschleger

Coin flipping is a cryptographic primitive for which strictly better protocols exist if the players are not only allowed to exchange classical, but also quantum messages. During th…

The thermodynamic meaning of negative entropy

Lídia del Rio, Johan Aberg, Renato Renner +2

Landauer's erasure principle exposes an intrinsic relation between thermodynamics and information theory: the erasure of information stored in a system, S, requires an amount of wo…
