Logarithmic coherence: Operational interpretation of -norm coherence
Swapan Rana, Preeti Parashar, Andreas Winter +1
We show that the distillable coherence---which is equal to the relative entropy of coherence---is, up to a constant factor, always bounded by the -norm measure of coherence…
Efficient device-independent entanglement detection for multipartite systems
Flavio Baccari, Daniel Cavalcanti, Peter Wittek +1
Entanglement is one of the most studied properties of quantum mechanics for its application in quantum information protocols. Nevertheless, detecting the presence of entanglement i…
Semi-device-independent framework based on natural physical assumptions
Thomas Van Himbeeck, Erik Woodhead, Nicolas J. Cerf +2
The semi-device-independent approach provides a framework for prepare-and-measure quantum protocols using devices whose behavior must not be characterized nor trusted, except for a…
Generalized Laws of Thermodynamics in the Presence of Correlations
Manabendra Nath Bera, Arnau Riera, Maciej Lewenstein +1
The laws of thermodynamics, despite their wide range of applicability, are known to break down when systems are correlated with their environments. Here, we generalize thermodynami…
Hybrid annealing using a quantum simulator coupled to a classical computer
Tobias Graß, Maciej Lewenstein
Finding the global minimum in a rugged potential landscape is a computationally hard task, often equivalent to relevant optimization problems. Simulated annealing is a computationa…
Low-temperature thermometry can be enhanced by strong coupling
Luis A. Correa, Martí Perarnau-Llobet, Karen V. Hovhannisyan +3
We consider the problem of estimating the temperature of a very cold equilibrium sample. The temperature estimates are drawn from measurements performed on a quantum probe st…
Simultaneous measurement of two non-commuting quantum variables: Solution of a dynamical model
Martí Perarnau-Llobet, Theo M. Nieuwenhuizen
The possibility of performing simultaneous measurements in quantum mechanics is investigated in the context of the Curie-Weiss model for a projective measurement. Concretely, we co…
Randomness in Quantum Mechanics: Philosophy, Physics and Technology
Manabendra Nath Bera, Antonio Acín, Marek Kuś +2
This progress report covers recent developments in the area of quantum randomness, which is an extraordinarily interdisciplinary area that belongs not only to physics, but also to…
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…
Which-way double slit experiments and Born rule violation
James Q. Quach
In which-way double-slit experiments with perfect detectors, it is assumed that having a second detector at the slits is redundant, as it will not change the interference pattern.…
Sensitivity, quantum limits, and quantum enhancement of noise spectroscopies
Vito Giovanni Lucivero, Aleksandra Dimic, Jia Kong +2
We study the fundamental limits of noise spectroscopy using estimation theory, Faraday rotation probing of an atomic spin system, and squeezed light. We find a simple and general e…
Changing optical band structure with single photons
Andreas Albrecht, Tommaso Caneva, Darrick E. Chang
Achieving strong interactions between individual photons enables a wide variety of exciting possibilities in quantum information science and many-body physics. Cold atoms interface…
Simulating positive-operator-valued measures with projective measurements
Michał Oszmaniec, Leonardo Guerini, Peter Wittek +1
Standard projective measurements represent a subset of all possible measurements in quantum physics, defined by positive-operator-valued measures. We study what quantum measurement…
Resonator reset in circuit QED by optimal control for large open quantum systems
Samuel Boutin, Christian Kraglund Andersen, Jayameenakshi Venkatraman +2
We study an implementation of the open GRAPE (Gradient Ascent Pulse Engineering) algorithm well suited for large open quantum systems. While typical implementations of optimal cont…
Quantum Coherence as a Resource
Alexander Streltsov, Gerardo Adesso, Martin B. Plenio
The coherent superposition of states, in combination with the quantization of observables, represents one of the most fundamental features that mark the departure of quantum mechan…
Experimental multipartite entanglement and randomness certification of the W state in the quantum steering scenario
A. Máttar, P. Skrzypczyk, G. H. Aguilar +4
Recently [Cavalcanti \textit{et al.} Nat Commun \textbf{6}, 7941 (2015)] proposed a method to certify the presence of entanglement in asymmetric networks, where some users do not h…
Causal hierarchy of multipartite Bell nonlocality
Rafael Chaves, Daniel Cavalcanti, Leandro Aolita
As with entanglement, different forms of Bell nonlocality arise in the multipartite scenario. These can be defined in terms of relaxations of the causal assumptions in local hidden…
Energy as a detector of nonlocality of many-body spin systems
Jordi Tura, Gemma De las Cuevas, Remigiusz Augusiak +3
We present a method to show that low-energy states of quantum many-body interacting systems in one spatial dimension are nonlocal. We assign a Bell inequality to the Hamiltonian of…
Bell inequalities tailored to maximally entangled states
Alexia Salavrakos, Remigiusz Augusiak, Jordi Tura +3
Bell inequalities have traditionally been used to demonstrate that quantum theory is nonlocal, in the sense that there exist correlations generated from composite quantum states th…
All entangled states can demonstrate non-classical teleportation
Daniel Cavalcanti, Paul Skrzypczyk, Ivan Šupić
Quantum teleportation, the process by which Alice can transfer an unknown quantum state to Bob by using pre-shared entanglement and classical communication, is one of the cornersto…
Elementary Thermal Operations
Matteo Lostaglio, Álvaro M. Alhambra, Christopher Perry
To what extent do thermodynamic resource theories capture physically relevant constraints? Inspired by quantum computation, we define a set of elementary thermodynamic gates that o…
Non-signaling deterministic models for non-local correlations have to be uncomputable
Ariel Bendersky, Gabriel Senno, Gonzalo de la Torre +2
Quantum mechanics postulates random outcomes. However, a model making the same output predictions but in a deterministic manner would be, in principle, experimentally indistinguish…
Designing exotic many-body states of atomic spin and motion in photonic crystals
Marco T. Manzoni, Ludwig Mathey, Darrick E. Chang
Cold atoms coupled to photonic crystals constitute an exciting platform for exploring quantum many-body physics. Here we investigate the strong coupling between atomic internal ("s…
Robust Bell inequalities from communication complexity
Sophie Laplante, Mathieu Laurière, Alexandre Nolin +2
The question of how large Bell inequality violations can be, for quantum distributions, has been the object of much work in the past several years. We say that a Bell inequality is…
