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…

Thermodynamic interpretation to Stochastic Fisher Information and Single-Trajectory Speed Limits
Pedro B. Melo, Fernando Iemini, Diogo O. Soares-Pinto +2
The Fisher information (FI) metric is a Riemannian metric that allows a geometric treatment of stochastic thermodynamics, introducing the possibility of computing thermodynamic len…

Classical Geometric Fluctuation Relations
Pedro B. Melo, Sílvio M. Duarte Queirós, Diogo O. Soares-Pinto +1
Fisher Information (FI) is a quantity ubiquitously measured in such varied areas like metrology, machine learning, and biological complexity. Mathematically, it represents a lower…
