Quantifying and Bounding Spatiotemporal Correlations in Quantum Noise
Guilherme Zambon, Diogo O. Soares-Pinto
Spatial and temporal correlations in quantum noise challenge the local Markovian models commonly used in quantum information processing. We develop a unified operational framework…
The Apparatus Strikes Back: Momentum Conservation and the Cost of Spatial Superpositions
Lucas C. Céleri, Diogo O. Soares-Pinto, Daniel A. Turolla Vanzella
Preparing massive particles in coherent spatial superpositions is a central objective of modern quantum science, motivated by applications ranging from fundamental tests of quantum…
Ergotropic and passive contributions on the phase-space information geometry of Gaussian states
Ivan Medina, Camila Raupp, Pedro B. Melo +1
We establish a direct connection between quantum thermodynamics and information geometry by introducing an ergotropic decomposition of the Wigner-Fisher information for Gaussian qu…
Thermodynamics of the optical pumping process in Nitrogen-Vacancy centers
Ivan Medina, Sérgio R. Muniz, Elisa I. Goettems +1
The optical pumping process is a fundamental tool for quantum protocols using the electronic and nuclear spins in the Nitrogen-Vacancy (NV) centers platform. In this work, we explo…
Distinguishing Ordered Phases using Machine Learning and Classical Shadows
Leandro Morais, Tiago Pernambuco, Rodrigo G. Pereira +3
Classifying phase transitions is a fundamental and complex challenge in condensed matter physics. This work proposes a framework for identifying quantum phase transitions by combin…
Expressibility, entangling power and quantum average causal effect for causally indefinite circuits
Pedro C. Azado, Guilherme I. Correr, Alexandre Drinko +3
Parameterized quantum circuits are the core of new technologies such as variational quantum algorithms and quantum machine learning, which makes studying its properties a valuable…
