Spin-orbit maximally discordant mixed states
D. G. Braga, I. Fonseca, W. F. Balthazar +2
We introduce a proposal to prepare spin-obit maximally discordant mixed states by a linear optical circuit, with quantum bits (qubits) encoded in the polarization and transverse mo…
Quantum advantage in temporally flat measurement-based quantum computation
Michael de Oliveira, Luís S. Barbosa, Ernesto F. Galvão
Several classes of quantum circuits have been shown to provide a quantum computational advantage under certain assumptions. The study of ever more restricted classes of quantum cir…
Effect of induced transition on the quantum entanglement and coherence in two-coupled double quantum dots system
Zakaria Dahbi, Maron F. Anka, Mostafa Mansour +2
Studying quantum properties in solid-state systems is a significant avenue for research. In this scenario, double quantum dots (DQDs) appear as a versatile platform for technologic…
Quantifying Quantum Causal Influences
Lucas Hutter, Rafael Chaves, Ranieri Nery +2
Causal influences are at the core of any empirical science, the reason why its quantification is of paramount relevance for the mathematical theory of causality and applications. Q…
Coherence and contextuality in a Mach-Zehnder interferometer
Rafael Wagner, Anita Camillini, Ernesto F. Galvão
We analyse nonclassical resources in interference phenomena using generalized noncontextuality inequalities and basis-independent coherence witnesses. We use recently proposed ineq…
Non-Markovianity through entropy-based quantum thermodynamics
J. M. Z. Choquehuanca, F. M. de Paula, M. S. Sarandy
We introduce a generalized approach to characterize the non-Markovianity of quantum dynamical maps via breakdown of monotonicity of thermodynamic functions. By adopting an entropy-…
Continuous phase transition induced by non-Hermiticity in the quantum contact process model
Wen-Bin He, Jiasen Jin, Fernando Iemini +1
Non-Hermitian quantum system recently have attracted a lots of attentions theoretically and experimentally. However, the results based on the single-particle picture may not apply…
Quantum-based solution of time-dependent complex Riccati equations
D. Martínez-Tibaduiza, C. González-Arciniegas, C. Farina +2
Using the Wei-Norman theory we obtain a time-dependent complex Riccati equation (TDCRE) as the solution of the time evolution operator (TEO) of quantum systems described by time-de…
Inequalities witnessing coherence, nonlocality, and contextuality
Rafael Wagner, Rui Soares Barbosa, Ernesto F. Galvão
Quantum coherence, nonlocality, and contextuality are key resources for quantum advantage in metrology, communication, and computation. We introduce a graph-based approach to deriv…
Quantum Stirling engine based on dinuclear metal complexes
Clebson Cruz, Hamid-Reza Rastegar-Sedehi, Maron F. Anka +2
Low-dimensional metal complexes are versatile materials with tunable physical and chemical properties that make these systems promising platforms for caloric applications. In this…
Algebraic approach to a two-qubit quantum thermal machine
A. C. Duriez, D. Martínez-Tibaduiza, A. Z. Khoury
Algebraic methods for solving time dependent Hamiltonians are used to investigate the performance of quantum thermal machines. We investigate the thermodynamic properties of an eng…
Quantum state inference from coarse-grained descriptions: analysis and an application to quantum thermodynamics
Raúl O. Vallejos, Pedro Silva Correia, Paola Concha Obando +3
The characterization of physical systems relies on the observable properties which are measured, and how such measurements are performed. Here we analyze two ways of assigning a de…
Reconstructing the full modal structure of photonic states by stimulated emission tomography
Arne Keller, Antonio Zelaquett Khoury, Nicolas Fabre +4
Stimulated emission tomography is a powerful and successful technique to both improve the resolution and experimentally simplify the task of determining the modal properties of bip…
Dynamical Casimir effects with atoms: from the emission of photon pairs to geometric phases
François Impens, Reinaldo de Melo e Souza, Guilherme C. Matos +1
The coupling between a moving ground-state atom and the quantum electromagnetic field is at the origin of several intriguing phenomena ranging from the dynamical Casimir emission o…
Quantum circuit compilation and hybrid computation using Pauli-based computation
Filipa C. R. Peres, Ernesto F. Galvão
Pauli-based computation (PBC) is driven by a sequence of adaptively chosen, non-destructive measurements of Pauli observables. Any quantum circuit written in terms of the Clifford+…
Quantum Vacuum Sagnac Effect
Guilherme C. Matos, Reinaldo de Melo e Souza, Paulo A. Maia Neto +1
We report on the quantum electrodynamical analogue of a Sagnac phase induced by the fast rotation of a neutral nanoparticle onto atomic waves propagating in its vicinity. The quant…
Nonadiabatic coupled-qubit Otto cycle with bidirectional operation and efficiency gains
Cleverson Cherubim, Thiago R. de Oliveira, Daniel Jonathan
We study a quantum Otto cycle that uses a 2-qubit working substance whose Hamiltonian does not commute with itself at different times during unitary strokes. We investigate how the…
