U(1) Wilson lattice gauge theories in digital quantum simulators
Christine Muschik, Markus Heyl, Esteban Martinez +7
Lattice gauge theories describe fundamental phenomena in nature, but calculating their real-time dynamics on classical computers is notoriously difficult. In a recent publication […
Efficient tomography of a quantum many-body system
B. P. Lanyon, C. Maier, M. Holzäpfel +10
Quantum state tomography (QST) is the gold standard technique for obtaining an estimate for the state of small quantum systems in the laboratory. Its application to systems with mo…
Direct observation of dynamical quantum phase transitions in an interacting many-body system
P. Jurcevic, H. Shen, P. Hauke +7
Dynamical quantum phase transitions (DQPTs) extend the concept of phase transitions and thus universality to the non-equilibrium regime. In this letter, we investigate DQPTs in a s…
Coherent Inflation for Large Quantum Superpositions of Microspheres
Oriol Romero-Isart
We show that coherent inflation, namely quantum dynamics generated by inverted conservative potentials acting on the center of mass of a massive object, is an enabling tool to prep…
Quantum theory from rules on information acquisition
Philipp A Hoehn
We summarise a recent reconstruction of the quantum theory of qubits from rules constraining an observer's acquisition of information about physical systems. This review of [arXiv:…
Distribution of high-dimensional entanglement via an intra-city free-space link
Fabian Steinlechner, Sebastian Ecker, Matthias Fink +5
Quantum entanglement is a fundamental resource in quantum information processing and its distribution between distant parties is a key challenge in quantum communications. Increasi…
1-out-of-2 Oblivious transfer using flawed Bit-string quantum protocol
Martin Plesch, Marcin Pawlowski, Matej Pivoluska
Oblivious transfer (OT) is an important tool in cryptography. It serves as a subroutine to other complex procedures of both theoretical and practical significance. Common attribute…
Demonstrating an absolute quantum advantage in direct absorption measurement
Paul-Antoine Moreau, Javier Sabines-Chesterking, Rebecca Whittaker +5
Engineering apparatus that harness quantum theory offers practical advantages over current technology. A fundamentally more powerful prospect is the long-standing prediction that s…
Sub-shot-noise transmission measurement using optically gated single photons
J. Sabines-Chesterking, R. Whittaker, S. K. Joshi +7
Harnessing the unique properties of quantum mechanics offers the possibility to deliver new technologies that can fundamentally outperform their classical counterparts. These techn…
A Coherent Quantum Annealer with Rydberg Atoms
Alexander W. Glaetzle, Rick M. W. van Bijnen, Peter Zoller +1
There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring co…
Quantifying the Momentum Correlation between Two Light Beams by Detecting One
Armin Hochrainer, Mayukh Lahiri, Radek Lapkiewicz +2
We report a measurement of the transverse momentum correlation between two photons by detecting only one of them. Our method uses two identical sources in an arrangement, in which…
Quantum State Transfer via Noisy Photonic and Phononic Waveguides
Benoît Vermersch, Pierre-Olivier Guimond, Hannes Pichler +1
We describe a quantum state transfer protocol, where a quantum state of photons stored in a first cavity can be faithfully transferred to a second distant cavity via an infinite 1D…
Quantum repeaters based on trapped ions with decoherence free subspace encoding
M. Zwerger, B. P. Lanyon, T. E. Northup +3
Quantum repeaters provide an efficient solution to distribute Bell pairs over arbitrarily long distances. While scalable architectures are demanding regarding the number of qubits…
Cosmic Bell Test: Measurement Settings from Milky Way Stars
Johannes Handsteiner, Andrew S. Friedman, Dominik Rauch +17
Bell's theorem states that some predictions of quantum mechanics cannot be reproduced by a local-realist theory. That conflict is expressed by Bell's inequality, which is usually d…
Quantum control of photonic entanglement with a single sub-wavelength structure
Alexander Büse, Mathieu L. Juan, Nora Tischler +4
Quantum entanglement is the basic resource for most quantum information schemes. A fundamental problem of using photonic states as carriers of quantum information is that they inte…
Flexible resources for quantum metrology
Nicolai Friis, Davide Orsucci, Michalis Skotiniotis +4
Quantum metrology offers a quadratic advantage over classical approaches to parameter estimation problems by utilizing entanglement and nonclassicality. However, the hurdle of actu…
Twin Photon Correlations in Single-Photon Interference
Mayukh Lahiri, Armin Hochrainer, Radek Lapkiewicz +2
We show that it is possible to generate a novel single-photon fringe pattern by using two spatially separated identical bi-photon sources. The fringes are similar to the ones obser…
Entanglement by Path Identity
Mario Krenn, Armin Hochrainer, Mayukh Lahiri +1
Quantum entanglement is one of the most prominent features of quantum mechanics and forms the basis of quantum information technologies. Here we present a novel method for the crea…
Experimental Verification of an Indefinite Causal Order
Giulia Rubino, Lee A. Rozema, Adrien Feix +5
Investigating the role of causal order in quantum mechanics has recently revealed that the causal distribution of events may not be a-priori well-defined in quantum theory. While t…
Composing decoherence functionals
Paul Boes, Miguel Navascues
Quantum Measure Theory (QMT) is a generalization of quantum theory where physical predictions are computed from a matrix known as \emph{decoherence functional} (DF). Previous works…
Genuine-multipartite entanglement criteria based on positive maps
Fabien Clivaz, Marcus Huber, Ludovico Lami +1
Positive maps applied to a subsystem of a bipartite quantum state constitute a central tool in characterising entanglement. In the multipartite case, however, the direct applicatio…
Fault-tolerant interface between quantum memories and quantum processors
Hendrik Poulsen Nautrup, Nicolai Friis, Hans J. Briegel
Topological error correction codes are promising candidates to protect quantum computations from the deteriorating effects of noise. While some codes provide high noise thresholds…
