Stochastic thermodynamics of a quantum dot coupled to a finite-size reservoir
Saulo V. Moreira, Peter Samuelsson, Patrick P. Potts
In nano-scale systems coupled to finite-size reservoirs, the reservoir temperature may fluctuate due to heat exchange between the system and the reservoirs. To date, a stochastic t…
Time-Dependent Dephasing and Quantum Transport
Saulo V. Moreira, Breno Marques, Fernando L. Semião
The investigation of the phenomenon of dephasing assisted quantum transport, which happens when the presence of dephasing benefits the efficiency of this process, has been mainly f…
Quantum versus classical transport of energy in coupled two-level systems
I. Medina, S. V. Moreira, F. L. Semião
We consider the problem of energy transport in a chain of coupled quantum systems with the goal of shedding light on how nonclassical resources can affect transport. We study the c…
In and out of equilibrium quantum metrology with mean-field quantum criticality
Sascha Wald, Saulo V. Moreira, Fernando L. Semião
We study the influence that collective transition phenomena have on quantum metrological protocols. The single spherical quantum spin (SQS) serves as stereotypical toy model that a…
Enhancing quantum transport efficiency by tuning non-Markovian dephasing
Saulo V. Moreira, Breno Marques, Rafael R. Paiva +3
We consider the problem of energy transport in a chain of coupled dissipative quantum systems in the presence of non-Markovian dephasing. We use a model of non-Markovianity which i…
Investigating nonclassicality in nonlinear electronic spectroscopy
Saulo V. Moreira, Fernando L. Semião
In this work, we establish a connection between nonlinear electronic spectroscopy and the protocol for the non-disturbance condition, the non-fullfilment of which is a witness of n…
Quantifying quantum invasiveness
Saulo V. Moreira, Marcelo Terra Cunha
We propose a resource theory of the quantum invasiveness of general quantum operations, i.e., those defined by quantum channels in Leggett-Garg scenarios. We are then able to compa…
Connecting measurement invasiveness to optimal metrological scenarios
Saulo V. Moreira, Gerardo Adesso, Luis A. Correa +3
The connection between the Leggett-Garg inequality and optimal scenarios from the point of view of quantum metrology is investigated for perfect and noisy general dichotomic measur…
Modeling Leggett-Garg-inequality violation
Saulo V. Moreira, Arne Keller, Thomas Coudreau +1
The Leggett-Garg inequality is a widely used test of the "quantumness" of a system, and involves correlations between measurements realized at different times. According to its wid…
