Long Distance Coupling of a Quantum Mechanical Oscillator to the Internal States of an Atomic Ensemble
B. Vogell, T. Kampschulte, M. T. Rakher +4
We propose and investigate a hybrid optomechanical system consisting of a micro-mechanical oscillator coupled to the internal states of a distant ensemble of atoms. The interaction…
Two-mode squeezed states as Schrodinger-cat-like states
E. Oudot, P. Sekatski, F. Fröwis +2
In recent years, there has been an increased interest in the generation of superposition of coherent states with opposite phases, the so-called photonic Schrodinger-cat states. The…
Improved HDRG decoders for qudit and non-Abelian quantum error correction
Adrian Hutter, Daniel Loss, James R. Wootton
Hard-decision renormalization group (HDRG) decoders are an important class of decoding algorithms for topological quantum error correction. Due to their versatility, they have been…
Detection of weak forces based on noise-activated switching in bistable optomechanical systems
Samuel Aldana, Christoph Bruder, Andreas Nunnenkamp
We propose to use cavity optomechanical systems in the regime of optical bistability for the detection of weak harmonic forces. Due to the optomechanical coupling an external force…
Comparing different approaches for generating random numbers device-independently using a photon pair source
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +6
What is the most efficient way to generate random numbers device-independently using a photon pair source based on spontaneous parametric down conversion (SPDC)? We consider this q…
Tighter quantum uncertainty relations follow from a general probabilistic bound
Florian Fröwis, Roman Schmied, Nicolas Gisin
Uncertainty relations (URs) like the Heisenberg-Robertson or the time-energy UR are often considered to be hallmarks of quantum theory. Here, a simple derivation of these URs is pr…
Diamond Nanophotonics
Igor Aharonovich, Elke Neu
The burgeoning field of nanophotonics has grown to be a major research area, primarily because of the ability to control and manipulate single quantum systems (emitters) and single…
Cavity-Modified Collective Rayleigh Scattering of Two Atoms
René Reimann, Wolfgang Alt, Tobias Kampschulte +5
We report on the observation of cooperative radiation of exactly two neutral atoms strongly coupled to the single mode field of an optical cavity, which is close to the lossless-ca…
Sympathetic cooling of a membrane oscillator in a hybrid mechanical-atomic system
Andreas Jöckel, Aline Faber, Tobias Kampschulte +3
Sympathetic cooling with ultracold atoms and atomic ions enables ultralow temperatures in systems where direct laser or evaporative cooling is not possible. It has so far been limi…
Reflection Positivity for Parafermions
Arthur Jaffe, Fabio L. Pedrocchi
We establish reflection positivity for Gibbs trace states for a class of gauge-invariant, reflection-invariant Hamiltonians describing parafermion interactions on a lattice. We rel…
Quantum State Tomography of a Single Qubit: Comparison of Methods
Roman Schmied
The tomographic reconstruction of the state of a quantum-mechanical system is an essential component in the development of quantum technologies. We present an overview of different…
Error Thresholds for Abelian Quantum Double Models: Increasing the bit-flip Stability of Topological Quantum Memory
Ruben S. Andrist, James R. Wootton, Helmut G. Katzgraber
Current approaches for building quantum computing devices focus on two-level quantum systems which nicely mimic the concept of a classical bit, albeit enhanced with additional quan…
Challenging preconceptions about Bell tests with photon pairs
V. Caprara Vivoli, P. Sekatski, J. -D. Bancal +7
Motivated by very recent experiments, we consider a scenario "à la Bell" in which two protagonists test the Clauser-Horne-Shimony-Holt (CHSH) inequality using a photon-pair source…
Witnessing single-photon entanglement with local homodyne measurements: analytical bounds and robustness to losses
Melvyn Ho, Olivier Morin, Jean-Daniel Bancal +3
Single-photon entanglement is one of the primary resources for quantum networks, including quantum repeater architectures. Such entanglement can be revealed with only local homodyn…
Quantum interference distinguishes between constitutional isomers
Jens Tüxen, Stefan Gerlich, Sandra Eibenberger +2
Matter waves, as introduced by de Broglie in 1923, are a fundamental quantum phenomenon, describing the delocalized center of mass motion of massive bodies and we show here their s…
Influence of conformational molecular dynamics on matter wave interferometry
Michael Gring, Stefan Gerlich, Sandra Eibenberger +9
We investigate the influence of thermally activated internal molecular dynamics on the phase shifts of matter waves inside a molecule interferometer. While de Broglie physics gener…
Ultracold Chemistry and its Reaction Kinetics
Florian Richter, Daniel Becker, Cédric Bény +3
We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key ro…
Linking Measures for Macroscopic Quantum States via Photon-Spin Mapping
F. Fröwis, N. Sangouard, N. Gisin
We review and compare several measures that identify quantum states that are "macroscopically quantum". These measures were initially formulated either for photonic systems or spin…
Using Mathematica for Quantum Mechanics: A Student's Manual
Roman Schmied
This book is an attempt to help students transform all of the concepts of quantum mechanics into concrete computer representations, which can be constructed, evaluated, analyzed, a…
Breakdown of Surface Code Error Correction Due to Coupling to a Bosonic Bath
Adrian Hutter, Daniel Loss
We consider a surface code suffering decoherence due to coupling to a bath of bosonic modes at finite temperature and study the time available before the unavoidable breakdown of e…
Nano-optical observation of cascade switching in a parallel superconducting nanowire single photon detector
Robert M. Heath, Michael G. Tanner, Alessandro Casaburi +5
The device physics of parallel-wire superconducting nanowire single photon detectors is based on a cascade process. Using nano-optical techniques and a parallel wire device with sp…
How difficult it is to prove the quantumness of macroscropic states?
Pavel Sekatski, Nicolas Gisin, Nicolas Sangouard
General wisdom tells us that if two quantum states are ``macroscopically distinguishable'' then their superposition should be hard to observe. We make this intuition precise and ge…
Real-time single-molecule imaging of quantum interference
Thomas Juffmann, Adriana Milic, Michael Müllneritsch +6
The observation of interference patterns in double-slit experiments with massive particles is generally regarded as the ultimate demonstration of the quantum nature of these object…
Relative Thermalization
Lidia del Rio, Adrian Hutter, Renato Renner +1
When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that…
