Scalable Bell inequalities for qubit graph states and robust self-testing
F. Baccari, R. Augusiak, I. Šupić +2
Bell inequalities constitute a key tool in quantum information theory: they not only allow one to reveal nonlocality in composite quantum systems, but, more importantly, they can b…
Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements
Itay Shomroni, Amir Youssefi, Nick Sauerwein +5
While quantum mechanics imposes a fundamental limit on the precision of interferometric measurements of mechanical motion due to measurement backaction, the nonlinear nature of the…
Deterministic creation of entangled atom-light Schrödinger-cat states
Bastian Hacker, Stephan Welte, Severin Daiss +4
Quantum physics allows for entanglement between microscopic and macroscopic objects, described by discrete and continuous variables, respectively. As in Schrödinger's famous cat ge…
Classification of Matrix-Product Unitaries with Symmetries
Zongping Gong, Christoph Sünderhauf, Norbert Schuch +1
We prove that matrix-product unitaries (MPUs) with on-site unitary symmetries are completely classified by the (chiral) index and the cohomology class of the symmetry group , pr…
Self-testing with finite statistics enabling the certification of a quantum network link
Jean-Daniel Bancal, Kai Redeker, Pavel Sekatski +2
Self-testing is a method to certify devices from the result of a Bell test. Although examples of noise tolerant self-testing are known, it is not clear how to deal efficiently with…
Advances in Quantum Reinforcement Learning
Vedran Dunjko, Jacob M. Taylor, Hans J. Briegel
In recent times, there has been much interest in quantum enhancements of machine learning, specifically in the context of data mining and analysis. Reinforcement learning, an inter…
Nonadiabatic dynamics and geometric phase of an ultrafast rotating electron spin
Xing-Yan Chen, Tongcang Li, Zhang-qi Yin
The spin in a rotating frame has attracted a lot of attentions recently, as it deeply relates to both fundamental physics such as pseudo-magnetic field and geometric phase, and app…
Bounds on the capacity and power of quantum batteries
Sergi Julia-Farre, Tymoteusz Salamon, Arnau Riera +2
Quantum batteries, composed of quantum cells, are expected to outperform their classical analogs. The origin of such advantages lies in the role of quantum correlations, which may…
Anisotropic quantum emitter interactions in two-dimensional photonic-crystal baths
A. González-Tudela, F. Galve
Quantum emitters interacting with two-dimensional photonic-crystal baths experience strong and anisotropic collective dissipation when they are spectrally tuned to 2D Van-Hove sing…
Single photons by quenching the vacuum
Eduardo Sánchez-Burillo, Luis Martín-Moreno, Juan José García-Ripoll +1
Heisenberg's uncertainty principle implies that the quantum vacuum is not empty but fluctuates. These fluctuations can be converted into radiation through nonadiabatic changes in t…
Universal Uhrig dynamical decoupling for bosonic systems
Margret Heinze, Robert Koenig
We construct efficient deterministic dynamical decoupling schemes protecting continuous variable degrees of freedom. Our schemes target decoherence induced by quadratic system-bath…
Thermodynamic length in open quantum systems
Matteo Scandi, Martí Perarnau-Llobet
The dissipation generated during a quasistatic thermodynamic process can be characterised by introducing a metric on the space of Gibbs states, in such a way that minimally-dissipa…
Collective operations can extremely reduce work fluctuations
Martí Perarnau-Llobet, Raam Uzdin
We consider work extraction from copies of a quantum system. When the same work-extraction process is implemented on each copy, the relative size of fluctuations is expected to…
Universal quantum gates between nitrogen-vacancy centers in a levitated nanodiamond
Xing-Yan Chen, Zhang-qi Yin
We propose a scheme to realize universal quantum gates between nitrogen-vacancy (NV) centers in an optically trapped nanodiamond, through uniform magnetic field induced coupling be…
Stochastic Integral Representation for the Dynamics of Disordered Systems
Ivana Kurecic, Tobias J. Osborne
The dynamics of interacting quantum systems in the presence of disorder is studied and an exact representation for disorder-averaged quantities via Ito stochastic calculus is obtai…
Quantum Simulation and Optimization in Hot Quantum Networks
Martin J. A. Schuetz, Benoît Vermersch, Gerhard Kirchmair +4
We propose and analyze a setup based on (solid-state) qubits coupled to a common multi-mode transmission line, which allows for coherent spin-spin interactions over macroscopic on-…
Optical Backaction-Evading Measurement of a Mechanical Oscillator
Itay Shomroni, Liu Qiu, Daniel Malz +2
Quantum mechanics imposes a limit on the precision of a continuous position measurement of a harmonic oscillator, as a result of quantum backaction arising from quantum fluctuation…
Hybrid Architecture for Engineering Magnonic Quantum Networks
C. C. Rusconi, M. J. A. Schuetz, J. Gieseler +2
We show theoretically that a network of superconducting loops and magnetic particles can be used to implement magnonic crystals with tunable magnonic band structures. In our approa…
Quantifying Superpositions Between Quantum Evolutions
Manabendra Nath Bera
Quantum mechanics allows coherent superposition between different states of matter. This quality is responsible for major non-classical phenomena that occur in quantum systems. Bey…
Higher dimensional entanglement without correlations
Waldemar Klobus, Wieslaw Laskowski, Tomasz Paterek +2
It has been demonstrated both theoretically and experimentally that genuine multipartite entanglement between qubits can exist even in the absence of multipartite correlations. Her…
Measurement-Disturbance Tradeoff Outperforming Optimal Cloning
Lukas Knips, Jan Dziewior, Anna-Lena K. Hashagen +3
One of the characteristic features of quantum mechanics is that every measurement that extracts information about a general quantum system necessarily causes an unavoidable disturb…
Discrete And Differentiable Entanglement Transformations
David Sauerwein, Katharina Schwaiger, Barbara Kraus
The study of transformations among pure states via Local Operations assisted by Classical Communication (LOCC) plays a central role in entanglement theory. The main emphasis of the…
Dynamics of quantum measurements employing two Curie-Weiss apparatuses
Martí Perarnau-Llobet, Theo M. Nieuwenhuizen
Two types of quantum measurements, measuring the spins of an entangled pair and attempting to measure a spin at either of two positions, are analysed dynamically by apparatuses of…

Shin-Liang Chen, Costantino Budroni, Yeong-Cherng Liang +1
In a recent work [Phys. Rev. Lett. 116, 240401 (2016)], a framework known by the name of "assemblage moment matrices" (AMMs) has been introduced for the device-independent quantifi…
