Device-independent Randomness Expansion with Entangled Photons
Lynden K. Shalm, Yanbao Zhang, Joshua C. Bienfang +12
With the growing availability of experimental loophole-free Bell tests, it has become possible to implement a new class of device-independent random number generators whose output…
Fast and simple quantum state estimation
Daniel Uzcategui Contreras, Gabriel Senno, Dardo Goyeneche
We present an iterative method to solve the multipartite quantum state estimation problem. We demonstrate convergence for any informationally complete set of generalized quantum me…
Universal Limitations on Quantum Key Distribution over a Network
Siddhartha Das, Stefan Bäuml, Marek Winczewski +1
We consider the distribution of secret keys, both in a bipartite and a multipartite (conference) setting, via a quantum network and establish a framework to obtain bounds on the ac…
Self-testing and certification using trusted quantum inputs
Ivan Šupić, Matty J. Hoban, Laia Domingo Colomer +1
Device-independent certification of quantum devices is of crucial importance for the development of secure quantum information protocols. So far, the most studied scenario correspo…
Statistical properties of the quantum internet
Samuraí Brito, Askery Canabarro, Rafael Chaves +1
Steady technological advances are paving the way for the implementation of the quantum internet, a network of locations interconnected by quantum channels. Here we propose a model…
Speed-ups to isothermality: Enhanced quantum thermal machines through control of the system-bath coupling
Nicola Pancotti, Matteo Scandi, Mark T. Mitchison +1
Isothermal transformations are minimally dissipative but slow processes, as the system needs to remain close to thermal equilibrium along the protocol. Here, we show that smoothly…
Bounding sets of sequential quantum correlations and device-independent randomness certification
Joseph Bowles, Flavio Baccari, Alexia Salavrakos
An important problem in quantum information theory is that of bounding sets of correlations that arise from making local measurements on entangled states of arbitrary dimension. Cu…
Attaining Carnot Efficiency with Quantum and Nanoscale Heat Engines
Mohit Lal Bera, Maciej Lewenstein, Manabendra Nath Bera
A heat engine operating in the one-shot finite-size regime, where systems composed of a small number of quantum particles interact with hot and cold baths and are restricted to one…
Quantum work statistics close to equilibrium
Matteo Scandi, Harry J. D. Miller, Janet Anders +1
We study the statistics of work, dissipation, and entropy production of a quantum quasi-isothermal process, where the system remains close to the thermal equilibrium along the tran…
Simulating Lattice Gauge Theories within Quantum Technologies
M. C. Bañuls, R. Blatt, J. Catani +17
Lattice gauge theories, which originated from particle physics in the context of Quantum Chromodynamics (QCD), provide an important intellectual stimulus to further develop quantum…
Exposure of subtle multipartite quantum nonlocality
M. M. Taddei, T. L. Silva, R. V. Nery +3
The celebrated Einstein-Podolsky-Rosen quantum steering has a complex structure in the multipartite scenario. We show that a naively defined criterion for multipartite steering all…
Constructions of k-uniform and absolutely maximally entangled states beyond maximum distance codes
Zahra Raissi, Adam Teixido, Christian Gogolin +1
Pure multipartite quantum states of n parties and local dimension q are called k-uniform if all reductions to k parties are maximally mixed. These states are relevant for our under…
Dynamics of many-body photon bound states in chiral waveguide QED
Sahand Mahmoodian, Giuseppe Calajó, Darrick E. Chang +2
We theoretically study the few- and many-body dynamics of photons in chiral waveguides. In particular, we examine pulse propagation through a system of two-level systems chiral…
Resource Preservability
Chung-Yun Hsieh
Resource theory is a general, model-independent approach aiming to understand the qualitative notion of resource quantitatively. In a given resource theory, free operations are phy…
Coherent optical and spin spectroscopy of nanoscale Pr3+:Y2O3
D. Serrano, C. Deshmukh, S. Liu +4
We investigate the potential for optical quantum technologies of Pr3+:Y2O3 in the form of monodisperse spherical nanoparticles. We measured optical inhomogeneous lines of 27 GHz, a…
Device-independent certification of tensor products of quantum states using single-copy self-testing protocols
Ivan Šupić, Daniel Cavalcanti, Joseph Bowles
Self-testing protocols are methods to determine the presence of shared entangled states in a device independent scenario, where no assumptions on the measurements involved in the p…
A quasiprobability distribution for heat fluctuations in the quantum regime
Amikam Levy, Matteo Lostaglio
The standard approach to deriving fluctuation theorems fails to capture the effect of quantum correlation and coherence in the initial state of the system. Here we overcome this di…
Quantum Inflation: A General Approach to Quantum Causal Compatibility
Elie Wolfe, Alejandro Pozas-Kerstjens, Matan Grinberg +3
Causality is a seminal concept in science: Any research discipline, from sociology and medicine to physics and chemistry, aims at understanding the causes that could explain the co…
Gaussian Thermal Operations and the Limits of Algorithmic Cooling
A. Serafini, M. Lostaglio, S. Longden +3
The study of thermal operations allows one to investigate the ultimate possibilities of quantum states and of nanoscale thermal machines. Whilst fairly general, these results typic…
In situ characterization of linear-optical networks in randomized boson sampling
Saleh Rahimi-Keshari, Sima Baghbanzadeh, Carlton M. Caves
We introduce a method for efficient, in situ characterization of linear-optical networks (LONs) in randomized boson-sampling (RBS) experiments. We formulate RBS as a distributed ta…
Experimental investigation of superdiffusion via coherent disordered Quantum Walks
Andrea Geraldi, Alessandro Laneve, Luis Diego Bonavena +6
Many disordered systems show a superdiffusive dynamics, intermediate between the diffusive one, typical of a classical stochastic process, and the so called ballistic behaviour, wh…
Bell inequalities tailored to the Greenberger-Horne-Zeilinger states of arbitrary local dimension
Remigiusz Augusiak, Alexia Salavrakos, Jordi Tura +1
In device-independent quantum information processing Bell inequalities are not only used as detectors of nonlocality, but also as certificates of relevant quantum properties. In or…
