Finite-Bandwidth Protection of a Three-Level Quantum Heat Engine Against Parasitic Heat Leaks
Gilberto Aparecido Prataviera, Marcos César de Oliveira
Finite-bandwidth reservoir engineering can suppress unwanted transitions in a quantum thermal machine, but a physical filter also introduces a finite response time. We study this c…
Stochastic dynamics from maximum entropy in action space
Fabricio de Souza Luiz, José Carlos Bellizotti Souza, Luísa Toledo Tude +1
We develop an information-theoretic formulation of stochastic dynamics in which the fundamental stochastic variable is the total action connecting spacetime points, rather than ind…
Perturbative Input-Output Theory of Floquet Cavity Magnonics and Magnon Energy Shifts
T. Aguiar, M. C. de Oliveira
We develop a perturbative input-output formalism to compute the reflectance and transmittance spectra of cavity magnonics systems subject to a Floquet modulation. The method exploi…
Nonreciprocal Multipartite Entanglement in a two-cavity magnomechanical system
Rizwan Ahmed, Hazrat Ali, Aamir Shehzad +3
We propose a theoretical scheme for the generation of nonreciprocal multipartite entanglement in a two-mode cavity magnomechanical system, consisting of two cross-microwave (MW) ca…
Controllable Fano-type optical response and four-wave mixing via magnetoelastic coupling in a opto-magnomechanical system
Amjad Sohail, Rizwan Ahmed, Jia-Xin Peng +4
We analytically investigate the Fano-type optical response and four-wave mixing (FWM) process by exploiting the magnetoelasticity of a ferromagnetic material. The deformation of th…
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…
Temperature of the three-state quantum walk
Luisa Toledo Tude, Marcos C. de Oliveira
Despite the coined quantum walk being a closed quantum system under a unitary evolution, its Hilbert space can be divided in two sub-spaces, which makes it possible for one to anal…
Unravelling the non-classicality role in Gaussian heat engines
A. de Oliveira Junior, M. C de Oliveira
At the heart of quantum thermodynamics lies a fundamental question about what is genuine "quantum" in quantum heat engines and how to seek this quantumness, so that thermodynamical…
Strong Subadditivity Lower Bound and Quantum Channels
L. R. S. Mendes, M. C. de Oliveira
We derive the strong subadditivity of the von Neumann entropy with a strict lower bound dependent on the distribution of quantum correlation in the system. We investigate the struc…
Staggered quantum walks with superconducting microwave resonators
Jalil Khatibi Moqadam, Marcos Cesar de Oliveira, Renato Portugal
The staggered quantum walk model on a graph is defined by an evolution operator that is the product of local operators related to two or more independent graph tessellations. A gra…
Staggered Quantum Walks with Hamiltonians
Renato Portugal, Marcos Cesar de Oliveira, Jalil Khatibi Moqadam
Quantum walks are recognizably useful for the development of new quantum algorithms, as well as for the investigation of several physical phenomena in quantum systems. Actual imple…
Temperature Measurement and Phonon Number Statistics of a Nanoelectromechanical Resonator
O. P. de Sá Neto, M. C. de Oliveira, G. J. Milburn
Measuring thermodynamic quantities can be easy or not, depending on the system that is being studied. For a macroscopic object, measuring temperatures can be as simple as measuring…
Quantum simulation of the Anderson Hamiltonian with an array of coupled nanoresonators: delocalization and thermalization effects
J. Lozada-Vera, A. Carrillo, O. P. de Sá Neto +3
The possibility of using nanoelectromechanical systems as a simulation tool for quantum many-body effects is explored. It is demonstrated that an array of electrostatically coupled…
Quantum walks on a circle with optomechanical systems
Jalil Khatibi Moqadam, Renato Portugal, Marcos Cesar de Oliveira
We propose an implementation of a quantum walk on a circle on an optomechanical system by encoding the walker on the phase space of a radiation field and the coin on a two-level st…
