Response of entanglement to annealed vis-à-vis quenched disorder in quantum spin models
Anindita Bera, Debasis Sadhukhan, Debraj Rakshit +2
We investigate bipartite entanglement in random quantum models at equilibrium. Depending on the intrinsic time scales associated with equilibration of the random parameters an…
The European Quantum Technologies Roadmap
Antonio Acín, Immanuel Bloch, Harry Buhrman +15
Within the last two decades, Quantum Technologies (QT) have made tremendous progress, moving from Noble Prize award-winning experiments on quantum physics into a cross-disciplinary…
Population mixing due to dipole-dipole interactions in a 1D array of multilevel atoms
Ewan Munro, Ana Asenjo-Garcia, Yiheng Lin +3
We examine theoretically how dipole-dipole interactions arising from multiple photon scattering lead to a modified distribution of ground state populations in a driven, ordered 1D…
Entanglement and secret-key-agreement capacities of bipartite quantum interactions and read-only memory devices
Siddhartha Das, Stefan Bäuml, Mark M. Wilde
A bipartite quantum interaction corresponds to the most general quantum interaction that can occur between two quantum systems in the presence of a bath. In this work, we determine…
Experimental nonlocality-based randomness generation with non-projective measurements
S. Gómez, A. Mattar, E. S. Gómez +4
We report on an optical setup generating more than one bit of randomness from one entangled bit (i.e. a maximally entangled state of two-qubits). The amount of randomness is certif…
What it takes to shun equilibration
R. Gallego, H. Wilming, J. Eisert +1
Numerous works have shown that under mild assumptions unitary dynamics inevitably leads to equilibration of physical expectation values if many energy eigenstates contribute to the…
Reaching the optomechanical strong coupling regime with a single atom in a cavity
Lukas Neumeier, Tracy E. Northup, Darrick E. Chang
A major goal within the field of optomechanics is to achieve the single-photon strong coupling regime, wherein even a mechanical displacement as small as the zero-point uncertainty…
Uniqueness of the joint measurement and the structure of the set of compatible quantum measurements
Leonardo Guerini, Marcelo Terra Cunha
We address the problem of characterising the compatible tuples of measurements that admit a unique joint measurement. We derive a uniqueness criterion based on the method of pertur…
Tunable two-photon quantum interference of structured light
Vincenzo D'Ambrosio, Gonzalo Carvacho, Iris Agresti +2
Structured photons are nowadays an interesting resource in classical and quantum optics due to the richness of properties they show under propagation, focusing and in their interac…
Activation of entanglement from quantum coherence and superposition
Lu-Feng Qiao, Jun Gao, Alexander Streltsov +11
Quantum entanglement and coherence are two fundamental features of nature, arising from the superposition principle of quantum mechanics. While considered as puzzling phenomena in…
Optimization of photon storage fidelity in ordered atomic arrays
M. T. Manzoni, M. Moreno-Cardoner, A. Asenjo-Garcia +3
A major application for atomic ensembles consists of a quantum memory for light, in which an optical state can be reversibly converted to a collective atomic excitation on demand.…
Fundamental limits to frequency estimation: A comprehensive microscopic perspective
Jan F. Haase, Andrea Smirne, Jan Kołodyński +2
We consider a scenario in which qubit-like probes are used to sense an external field that linearly affects their energy splitting. Following the frequency estimation approach in w…
Distinguishing computable mixtures of quantum states
Ignacio H. López Grande, Gabriel Senno, Gonzalo de la Torre +4
In this article we extend results from our previous work [Bendersky, de la Torre, Senno, Figueira and Acín, Phys. Rev. Lett. 116, 230406 (2016)] by providing a protocol to distingu…
A classification of open Gaussian dynamics
Daniel Grimmer, Eric Brown, Achim Kempf +2
We introduce a classification scheme for the generators of bosonic open Gaussian dynamics, providing instructive diagrams description for each type of dynamics. Using this classifi…
Strong-field approximation in a rotating frame: High-order harmonic emission from p states in bicircular fields
Emilio Pisanty, Álvaro Jiménez-Galán
High-order harmonic generation with bicircular fields - the combination of counter-rotating circularly polarized pulses at different frequencies - results in a series of short-wave…
A quantum Otto engine with finite heat baths: energy, correlations, and degradation
Alejandro Pozas-Kerstjens, Eric G. Brown, Karen V. Hovhannisyan
We study a driven harmonic oscillator operating an Otto cycle between two thermal baths of finite size. By making extensive use of the tools of Gaussian quantum mechanics, we direc…
Optical sectioning in induced coherence tomography with frequency-entangled photons
Adam Vallés, Gerard Jiménez, Luis José Salazar-Serrano +1
We demonstrate a different scheme to perform optical sectioning of a sample based on the concept of induced coherence [Zou et al., Phys. Rev. Lett. 67, 318 (1991)]. This can be vie…
Quantum critical metrology
Irénée Frérot, Tommaso Roscilde
Quantum metrology fundamentally relies upon the efficient management of quantum uncertainties. We show that, under equilibrium conditions, the management of quantum noise becomes e…
Optimal Photon Generation from Spontaneous Raman Processes in Cold Atoms
Melvyn Ho, Colin Teo, Hugues de Riedmatten +1
Spontaneous Raman processes in cold atoms have been widely used in the past decade for generating single photons. Here, we present a method to optimize their efficiencies for given…
Signal tracking beyond the time resolution of an atomic sensor by Kalman filtering
Ricardo Jiménez-Martínez, Jan Kolodynski, Charikleia Troullinou +3
We study causal waveform estimation (tracking) of time-varying signals in a paradigmatic atomic sensor, an alkali vapor monitored by Faraday rotation probing. We use Kalman filteri…
Self-testing multipartite entangled states through projections onto two systems
Ivan Šupić, Andrea Coladangelo, Remigiusz Augusiak +1
Finding ways to test the behaviour of quantum devices is a timely enterprise, especially in the light of the rapid development of quantum technologies. Device-independent self-test…
Almost quantum correlations violate the no-restriction hypothesis
Ana Belén Sainz, Yelena Guryanova, Antonio Acín +1
To identify which principles characterize quantum correlations, it is essential to understand in which sense this set of correlations differs from that of almost quantum correlatio…
Thermodynamics as a Consequence of Information Conservation
Manabendra Nath Bera, Arnau Riera, Maciej Lewenstein +2
Thermodynamics and information have intricate interrelations. Often thermodynamics is considered to be the logical premise to justify that information is physical - through Landaue…
Single-photon quantum contextuality on a chip
Andrea Crespi, Marco Bentivegna, Ioannis Pitsios +7
In classical physics, properties of the objects exist independently on the context, i.e. whether and how measurements are performed. Quantum physics showed this assumption to be wr…
