Scalable Architecture for a Room Temperature Solid-State Quantum Information Processor
Norman Y. Yao, Liang Jiang, Alexey V. Gorshkov +4
The realization of a scalable quantum information processor has emerged over the past decade as one of the central challenges at the interface of fundamental science and engineerin…
Microwave guiding of electrons on a chip
Johannes Hoffrogge, Roman Fröhlich, Mark A. Kasevich +1
Electrons travelling in free space have allowed to explore fundamental physics like the wave nature of matter, the Aharonov-Bohm and the Hanbury Brown-Twiss effect. Complementarily…
Trapping ions with lasers
Cecilia Cormick, Tobias Schaetz, Giovanna Morigi
This work theoretically addresses the trapping an ionized atom with a single valence electron by means of lasers, analyzing qualitatively and quantitatively the consequences of the…
Entanglement distillation by dissipation and continuous quantum repeaters
Karl Gerd H. Vollbrecht, Christine A. Muschik, J. Ignacio Cirac
Even though entanglement is very vulnerable to interactions with the environment, it can be created by purely dissipative processes. Yet, the attainable degree of entanglement is p…
Optomechanical sideband cooling of a micromechanical oscillator close to the quantum ground state
Remi Riviere, Samuel Deleglise, Stefan Weis +4
Cooling a mesoscopic mechanical oscillator to its quantum ground state is elementary for the preparation and control of low entropy quantum states of large scale objects. Here, we…
Controlling the quantum stereodynamics of ultracold bimolecular reactions
M. H. G. de Miranda, A. Chotia, B. Neyenhuis +6
Chemical reaction rates often depend strongly on stereodynamics, namely the orientation and movement of molecules in three-dimensional space. An ultracold molecular gas, with a tem…
Optically Levitating Dielectrics in the Quantum Regime: Theory and Protocols
Oriol Romero-Isart, Anika C. Pflanzer, Mathieu L. Juan +4
We provide a general quantum theory to describe the coupling of light with the motion of a dielectric object inside a high finesse optical cavity. In particular, we derive the tota…
Simulating quantum-optical phenomena with cold atoms in optical lattices
Carlos Navarrete-Benlloch, Inés de Vega, Diego Porras +1
We propose a scheme involving cold atoms trapped in optical lattices to observe different phenomena traditionally linked to quantum-optical systems. The basic idea consists of conn…
Quantum memories based on engineered dissipation
Fernando Pastawski, Lucas Clemente, Juan Ignacio Cirac
Storing quantum information for long times without disruptions is a major requirement for most quantum information technologies. A very appealing approach is to use self-correcting…
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…
Determination of the vacuum optomechanical coupling rate using frequency noise calibration
Michael Gorodetsky, Albert Schliesser, Georg Anetsberger +2
The strength of optomechanical interactions in a cavity optomechanical system can be quantified by a vacuum coupling rate $\vcr$ analogous to cavity quantum electrodynamics. This s…
Dynamical enhancement of spatial entanglement in massive particles
Michael Lubasch, Florian Mintert, Sandro Wimberger
We discuss dynamical enhancement of entanglement in a driven Bose-Hubbard model and find an enhancement of two orders of magnitude which is robust against fluctuations in experimen…
Strong-field above-threshold photoemission from sharp metal tips
Markus Schenk, Michael Krüger, Peter Hommelhoff
We present energy-resolved measurements of electron emission from sharp metal tips driven with low energy pulses from a few-cycle laser oscillator. We observe above-threshold photo…
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…
Hawking Radiation on an Ion Ring in the Quantum Regime
Birger Horstmann, Ralf Schützhold, Benni Reznik +2
This paper discusses a recent proposal for the simulation of acoustic black holes with ions. The ions are rotating on a ring with an inhomogeneous, but stationary velocity profile.…
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…
Strong and weak thermalization of infinite non-integrable quantum systems
Mari Carmen Bañuls, J. Ignacio Cirac, Matthew B. Hastings
When a non-integrable system evolves out of equilibrium for a long time, local observables are expected to attain stationary expectation values, independent of the details of the i…
Dissipatively driven entanglement of two macroscopic atomic ensembles
Christine A. Muschik, Eugene S. Polzik, J. Ignacio Cirac
Up to date, the life time of experimentally demonstrated entangled states has been limited, due to their fragility under decoherence and dissipation. Therefore, they are created un…
Optomechanically induced transparency
S. Weis, R. Riviere, S. Deleglise +4
Coherent interaction of laser radiation with multilevel atoms and molecules can lead to quantum interference in the electronic excitation pathways. A prominent example observed in…
