Quantum prepare-and-measure scenarios: concepts and methods
A. de Oliveira Junior, Santiago Zamora, Jonatan Bohr Brask +2
Prepare-and-measure scenarios are among the simplest and most widely used settings for quantum communication. A sender prepares a physical system in one of several possible states,…
Privacy in continuous-variable distributed quantum sensing
A. de Oliveira Junior, Anton L. Andersen, Benjamin Lundgren Larsen +5
Can a distributed network of quantum sensors estimate a global parameter while protecting every locally encoded value? We answer this question affirmatively by introducing and anal…
Heat as a witness of quantum properties
A. de Oliveira Junior, Jonatan Bohr Brask, Patryk Lipka-Bartosik
We present a new approach for witnessing quantum resources, such as entanglement and coherence, based on heat generation. Inspired by Maxwell's demon, we ask what the optimal heat…
Geometric and information-theoretic aspects of quantum thermodynamics
A de Oliveira Junior
In this thesis, I investigate various aspects of one of the most fundamental questions in thermodynamics: what state transformations can quantum systems undergo while interacting w…
Quantum catalysis in cavity quantum electrodynamics
A. de Oliveira Junior, Martí Perarnau-Llobet, Nicolas Brunner +1
Catalysis plays a key role in many scientific areas, most notably in chemistry and biology. Here we present a catalytic process in a paradigmatic quantum optics setup, namely the J…
Machine classification for probe based quantum thermometry
Fabrício S. Luiz, A. de Oliveira Junior, Felipe F. Fanchini +1
We consider probe-based quantum thermometry and show that machine classification can provide model-independent estimation with quantifiable error assessment. Our approach is based…
Fluctuation-dissipation relations for thermodynamic distillation processes
Tanmoy Biswas, A. de Oliveira Junior, Michał Horodecki +1
The fluctuation-dissipation theorem is a fundamental result in statistical physics that establishes a connection between the response of a system subject to a perturbation and the…
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…
