Significant-loophole-free test of Bell's theorem with entangled photons
Marissa Giustina, Marijn A. M. Versteegh, Sören Wengerowsky +19
Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster than the speed of light…
Sufficient separability criteria and linear maps
Maciej Lewenstein, Remigiusz Augusiak, Dariusz Chruściński +2
We study families of positive and completely positive maps acting on a bipartite system (with ). The maps have a property that when appl…
Atom-field dressed states in slow-light waveguide QED
Giuseppe Calajo, Francesco Ciccarello, Darrick Chang +1
We discuss the properties of atom-photon bound states in waveguide QED systems consisting of single or multiple atoms coupled strongly to a finite-bandwidth photonic channel. Such…
Work and entropy production in generalised Gibbs ensembles
M. Perarnau-Llobet, A. Riera, R. Gallego +2
Recent years have seen an enormously revived interest in the study of thermodynamic notions in the quantum regime. This applies both to the study of notions of work extraction in t…
Semi device independence of the BB84 protocol
Erik Woodhead
The BB84 quantum key distribution protocol is semi device independent in the sense that it can be shown to be secure if just one of the users' devices is restricted to a qubit Hilb…
Entanglement of an Impurity in a Few-Body One-Dimensional Ideal Bose System
M. A. García-March, A. S. Dehkharghani, N. T. Zinner
We study the correlation between an impurity and a small ensemble of bosonic particles in one dimension. Our study analyzes the one-body density matrix and calculates the correspon…
General method for constructing local-hidden-variable models for entangled quantum states
Daniel Cavalcanti, Leonardo Guerini, Rafael Rabelo +1
Entanglement allows for the nonlocality of quantum theory, which is the resource behind device-independent quantum information protocols. However, not all entangled quantum states…
The ultimate precision limits for noisy frequency estimation
Andrea Smirne, Jan Kolodynski, Susana F. Huelga +1
Quantum metrology protocols allow to surpass precision limits typical to classical statistics. However, in recent years, no-go theorems have been formulated, which state that typic…
Photon molecules in atomic gases trapped near photonic crystal waveguides
James S. Douglas, Tommaso Caneva, Darrick E. Chang
Realizing systems that support robust, controlled interactions between individual photons is an exciting frontier of nonlinear optics. To this end, one approach that has emerged re…
Self-testing protocols based on the chained Bell inequalities
Ivan Šupić, Remigiusz Augusiak, Alexia Salavrakos +1
Self testing is a device-independent technique based on non-local correlations whose aim is to certify the effective uniqueness of the quantum state and measurements needed to prod…
Energetics of correlations in interacting systems
Nicolai Friis, Marcus Huber, Martí Perarnau-Llobet
A fundamental connection between thermodynamics and information theory arises from the fact that correlations exhibit an inherent work value. For noninteracting systems this transl…
Genuine quantum coherence
Julio I. de Vicente, Alexander Streltsov
Any quantum resource theory is based on free states and free operations, i.e., states and operations which can be created and performed at no cost. In the resource theory of cohere…
Thermodynamic resource theories, non-commutativity and maximum entropy principles
Matteo Lostaglio, David Jennings, Terry Rudolph
We discuss some features of thermodynamics in the presence of multiple conserved quantities. We prove a generalisation of Landauer principle illustrating tradeoffs between the eras…
A strong loophole-free test of local realism
Lynden K. Shalm, Evan Meyer-Scott, Bradley G. Christensen +31
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated by placing the parti…
Trace-distance measure of coherence
Swapan Rana, Preeti Parashar, Maciej Lewenstein
We show that trace distance measure of coherence is a strong monotone for all qubit and, so called, states. An expression for the trace distance coherence for all pure states a…
Unbounded randomness certification using sequences of measurements
F. J. Curchod, M. Johansson, R. Augusiak +3
Unpredictability, or randomness, of the outcomes of measurements made on an entangled state can be certified provided that the statistics violate a Bell inequality. In the standard…
Towards resource theory of coherence in distributed scenarios
Alexander Streltsov, Swapan Rana, Manabendra Nath Bera +1
The search for a simple description of fundamental physical processes is an important part of quantum theory. One example for such an abstraction can be found in the distance lab p…
Squeezed-light spin noise spectroscopy
Vito Giovanni Lucivero, Ricardo Jiménez-Martínez, Jia Kong +1
We report quantum enhancement of Faraday rotation spin noise spectroscopy by polarization squeezing of the probe beam. Using natural abundance Rb in 100 Torr of N_2 buffer gas, and…
Maximal entanglement of two delocalized spin- particles
Markus Johansson
We describe the entanglement of two indistinguishable delocalized spin- particles in the simplest spatial configuration of three spatial modes with the constraint that…
Experimental loophole-free violation of a Bell inequality using entangled electron spins separated by 1.3 km
B. Hensen, H. Bernien, A. E. Dréau +16
For more than 80 years, the counterintuitive predictions of quantum theory have stimulated debate about the nature of reality. In his seminal work, John Bell proved that no theory…
Hybrid Entangled Entanglement in Vector Vortex Beams
Vincenzo D'Ambrosio, Gonzalo Carvacho, Francesco Graffitti +4
Light beams having a vectorial field structure - or polarization - that varies over the transverse profile and a central optical singularity are called vector-vortex (VV) beams and…
Assisted distillation of quantum coherence
E. Chitambar, A. Streltsov, S. Rana +3
We introduce and study the task of assisted coherence distillation. This task arises naturally in bipartite systems where both parties work together to generate the maximal possibl…
Asymptotic role of entanglement in quantum metrology
Remigiusz Augusiak, Jan Kolodynski, Alexander Streltsov +3
Quantum systems allow one to sense physical parameters beyond the reach of classical statistics---with resolutions greater than , where is the number of constituent partic…
Generation of fresh and pure random numbers for loophole-free Bell tests
Carlos Abellan, Waldimar Amaya, Daniel Mitrani +2
We demonstrate extraction of randomness from spontaneous-emission events less than 36 ns in the past, giving output bits with excess predictability below and strong metro…
