Single spontaneous photon as a coherent beamsplitter for an atomic matterwave
Jiří Tomkovič, Michael Schreiber, Joachim Welte +3
In spontaneous emission an atom in an excited state undergoes a transition to the ground state and emits a single photon. Associated with the emission is a change of the atomic mom…
On the Time-Dependent Analysis of Gamow Decay
Detlef Dürr, Robert Grummt, Martin Kolb
Gamow's explanation of the exponential decay law uses complex "eigenvalues" and exponentially growing "eigenfunctions". This raises the question, how Gamow's description fits into…
Correlation complementarity yields Bell monogamy relations
P. Kurzynski, T. Paterek, R. Ramanathan +2
We present a method to derive Bell monogamy relations by connecting the complementarity principle with quantum non-locality. The resulting monogamy relations are stronger than thos…
Laser Dressed Scattering of an Attosecond Electron Wave Packet
Justin Gagnon, Ferenc Krausz, Vladislav S. Yakovlev
We theoretically investigate the scattering of an attosecond electron wave packet launched by an attosecond pulse under the influence of an infrared laser field. As the electron sc…
Highly-efficient state-selective sub-microsecond photoionization detection of single atoms
Florian Henkel, Michael Krug, Julian Hofmann +3
We experimentally demonstrate a detection scheme suitable for state analysis of single optically trapped atoms in less than 1 μs with an overall detection efficiency η exceeding 98…
Inertial and gravitational mass in quantum mechanics
E. Kajari, N. L. Harshman, E. M. Rasel +3
We show that in complete agreement with classical mechanics, the dynamics of any quantum mechanical wave packet in a linear gravitational potential involves the gravitational and t…
Fisher information and multiparticle entanglement
Philipp Hyllus, Wiesław Laskowski, Roland Krischek +5
The Fisher information gives a limit to the ultimate precision achievable in a phase estimation protocol. It has been shown recently that the Fisher information for a linear tw…
Entanglement dynamics in open two-qubit systems via diffusive quantum trajectories
Carlos Viviescas, Ivonne Guevara, André R. R. Carvalho +2
We use quantum diffusive trajectories to prove that the time evolution of two-qubit entanglement under spontaneous emission can be fully characterized by optimal continuous monitor…
Permutationally invariant quantum tomography
Geza Toth, Witlef Wieczorek, David Gross +3
We present a scalable method for the tomography of large multiqubit quantum registers. It acquires information about the permutationally invariant part of the density operator, whi…
Non-classicality thresholds for multiqubit states - numerical analysis
Jacek Gruca, Wieslaw Laskowski, Marek Zukowski +4
States that strongly violate Bell's inequalities are required in many quantum informational protocols as, for example, in cryptography, secret sharing and the reduction of communic…
Stochastic simulation algorithm for the quantum linear Boltzmann equation
Marc Busse, Piotr Pietrulewicz, Heinz-Peter Breuer +1
We develop a Monte Carlo wave function algorithm for the quantum linear Boltzmann equation, a Markovian master equation describing the quantum motion of a test particle interacting…
Measuring nanomechanical motion with an imprecision far below the standard quantum limit
G. Anetsberger, E. Gavartin, O. Arcizet +5
We demonstrate a transducer of nanomechanical motion based on cavity enhanced optical near-fields capable of achieving a shot-noise limited imprecision more than 10 dB below the st…
Atom chip based generation of entanglement for quantum metrology
Max F. Riedel, Pascal Böhi, Yun Li +3
Atom chips provide a versatile `quantum laboratory on a microchip' for experiments with ultracold atomic gases. They have been used in experiments on diverse topics such as low-dim…
Resonant coupling of a Bose-Einstein condensate to a micromechanical oscillator
D. Hunger, S. Camerer, T. W. Haensch +4
We report experiments in which the vibrations of a micromechanical oscillator are coupled to the motion of Bose-condensed atoms in a trap. The interaction relies on surface forces…
Quantum Memories. A Review based on the European Integrated Project "Qubit Applications (QAP)"
C. Simon, M. Afzelius, J. Appel +21
We perform a review of various approaches to the implementation of quantum memories, with an emphasis on activities within the quantum memory sub-project of the EU Integrated Proje…
Molecular Feshbach dissociation as a source for motionally entangled atoms
Clemens Gneiting, Klaus Hornberger
We describe the dissociation of a diatomic Feshbach molecule due to a time-varying external magnetic field in a realistic trap and guide setting. An analytic expression for the asy…
