Performance analysis of continuous-variable quantum key distribution using non-Gaussian states
L. S. Aguiar, L. F. M. Borelli, J. A. Roversi +1
In this study, we analyze the efficiency of a protocol with discrete modulation of continuous variable non-Gaussian states, the coherent states having one photon added and then one…
Quantum annealing in the NISQ era: railway conflict management
Krzysztof Domino, Mátyás Koniorczyk, Krzysztof Krawiec +3
We are in the Noisy Intermediate-Scale Quantum (NISQ) devices' era, in which quantum hardware has become available for application in real-world problems. However, demonstrating th…
A Quantum Approach to the Discretizable Molecular Distance Geometry Problem
Carlile Lavor, Franklin Marquezino, Andres Oliveira +1
The Discretizable Molecular Distance Geometry Problem (DMDGP) aims to determine the three-dimensional protein structure using distance information from nuclear magnetic resonance e…
Tripartite State Characterization via Activated Bipartite Entanglement
L. G. E. Arruda, W. F. Balthazar, M. V. Moreira +3
We propose a procedure to identify and classify genuine tripartite entanglement in pure 3-qubit states via the Activated Bipartite Entanglement (ABE), which is defined here as the…
The three phases of quantum annealing: fast, slow, and very slow
Artur Soriani, Pierre Nazé, Marcus V. S. Bonança +2
Currently, existing quantum annealers have proven themselves as viable technology for the first practical applications in the noisy-intermediate-scale-quantum era. However, to full…
Generation of nonclassical states of light via truncation of mixed states
E. P. Mattos, A. Vidiella-Barranco
A possible way of generating nonclassical states of light, especially non-Gaussian states, is via the truncation of a given state in the Fock basis. In recent work, we presented an…
Quantum entanglement in a four-partite hybrid system containing three macroscopic subsystems
C. Corrêa, A. Vidiella-Barranco
The combination of different quantum systems may allow the exploration of the distinctive features of each system for the investigation of fundamental phenomena as well as for quan…
Environment-Assisted Shortcuts to Adiabaticity
Akram Touil, Sebastian Deffner
Envariance is a symmetry exhibited by correlated quantum systems. Inspired by this "quantum fact of life," we propose a novel method for shortcuts to adiabaticity which enables the…
Quantum state truncation using an optical parametric amplifier and a beamsplitter
E. P. Mattos, A. Vidiella-Barranco
We present a scheme of quantum state truncation in the Fock basis (quantum scissors), based on the combined action of a nondegenerate optical parametric amplifier and a beamsplitte…
Temperature estimation of an entangled pair of trapped ions
O. P. de Sá Neto, H. A. S. Costa, G. A. Prataviera +1
We apply estimation theory to a system formed by two interacting trapped ions. By using the Fisher matrix formalism, we introduce a simple scheme for estimation of the temperature…
Higher-dimensional Euclidean and non-Euclidean structures in planar circuit quantum electrodynamics
Alberto Saa, Eduardo Miranda, Francisco Rouxinol
We show that a recent proposal for simulating planar hyperbolic lattices with circuit quantum electrodynamics can be extended to accommodate also higher dimensional lattices in Euc…
Decoherence in the three-state quantum walk
Luísa Toledo Tude, Marcos C. de Oliveira
Quantum walks are dynamic systems with a wide range of applications in quantum computation and quantum simulation of analog systems, therefore it is of common interest to understan…
Diverging quantum speed limits: a herald of classicality
Pablo M. Poggi, Steve Campbell, Sebastian Deffner
When is the quantum speed limit (QSL) really quantum? While vanishing QSL times often indicate emergent classical behavior, it is still not entirely understood what precise aspects…
Eavesdropping on the Decohering Environment: Quantum Darwinism, Amplification, and the Origin of Objective Classical Reality
Akram Touil, Bin Yan, Davide Girolami +2
"How much information about a system can one extract from a fragment of the environment that decohered it?" is the central question of Qua…
Quantum communication complexity beyond Bell nonlocality
Joseph Ho, George Moreno, Samuraí Brito +8
Efficient distributed computing offers a scalable strategy for solving resource-demanding tasks such as parallel computation and circuit optimisation. Crucially, the communication…
Quantum Euler relation for local measurements
Akram Touil, Kevin Weber, Sebastian Deffner
In classical thermodynamics the Euler relation is an expression for the internal energy as a sum of the products of canonical pairs of extensive and intensive variables. For quantu…
Quantum sets of the multicolored-graph approach to contextuality
Lina Vandré, Marcelo Terra Cunha
The CHSH inequalities are the most famous examples of Bell inequalities. Cabello, Severini, and Winter (CSW) came up with a graph approach to noncontextuality inequalities, which c…
Emergence of noncontextuality under quantum Darwinism
Roberto D. Baldijão, Rafael Wagner, Cristhiano Duarte +2
Quantum Darwinism proposes that the proliferation of redundant information plays a major role in the emergence of objectivity out of the quantum world. Is this kind of objectivity…
Optomechanical quantum teleportation
Niccolò Fiaschi, Bas Hensen, Andreas Wallucks +4
Quantum teleportation, the faithful transfer of an unknown input state onto a remote quantum system, is a key component in long distance quantum communication protocols and distrib…
Semi-device-independent certification of entanglement in superdense coding
George Moreno, Ranieri Nery, Carlos de Gois +2
Superdense coding is a paradigmatic protocol in quantum information science, employing a quantum communication channel to send classical information more efficiently. As we show he…
Quantum and classical ergotropy from relative entropies
Akira Sone, Sebastian Deffner
The quantum ergotropy quantifies the maximal amount of work that can be extracted from a quantum state without changing its entropy. Given that the ergotropy can be expressed as th…
Energetic cost of Hamiltonian quantum gates
Sebastian Deffner
Landauer's principle laid the main foundation for the development of modern thermodynamics of information. However, in its original inception the principle relies on semiformal arg…
Ergotropy from quantum and classical correlations
Akram Touil, Barış Çakmak, Sebastian Deffner
It is an established fact that quantum coherences have thermodynamic value. The natural question arises, whether other genuine quantum properties such as entanglement can also be e…
Using a resource theoretic perspective to witness and engineer quantum generalized contextuality for prepare-and-measure scenarios
Rafael Wagner, Roberto D. Baldijão, Alisson Tezzin +1
We employ the resource theory of generalized contextuality as a tool for analyzing the structure of prepare-and-measure scenarios. We argue that this framework simplifies proofs of…
