Thermodynamics of Ahn--Doherty--Landahl Continuous Quantum Error Correction
Juan Garcia-Nila, Pedro B. Melo, Lucas Johns
Continuous quantum error correction (CQEC) replaces discrete syndrome measurements and recovery operations with continuous syndrome extraction and real-time Hamiltonian feedback. H…
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…
Pointwise mutual information bounded by stochastic Fisher information
Pedro B. Melo
How much information about an unknown parameter can be assigned to one realized outcome, and how is that information constrained by the sensitivity of the same outcome? We derive u…
Stochastic Quantum Information Geometry and Speed Limits at the Trajectory Level
Pedro B. Melo, Pedro V. Paraguassú, Sílvio M. Duarte Queirós +3
In quantum metrology, precision is typically characterized by an ensemble-averaged quantity, the quantum Fisher information (QFI), which averages over the fluctuations of individua…
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…
Stochastic thermodynamics of Fisher information
Pedro B. Melo, Sílvio M. Duarte Queirós, Welles A. M. Morgado
In this paper, we investigate the stochastic thermodynamics of Fisher information (FI), meaning we characterize both the \textit{fluctuations} of FI, introducing a parastatistics o…
Brownian Fluctuations of a non-confining potential
Pedro B. Melo, Pedro V. Paraguassú, Eduardo S. Nascimento +1
Brownian fluctuations arise for any quantity that depends on the stochastic variables of a Brownian particle. In this study, we explore the Brownian fluctuations of a bidimensional…
