Stochastic trajectories and excursions in a double quantum dot system
Guilherme Fiusa, Pedro E. Harunari, Alberto J. B. Rosal +2
We investigate the trajectory-level stochastic dynamics of a double quantum dot system using the formalism of stochastic excursions. An excursion is a sub-trajectory that begins wh…
Deterministic Equations for Feedback Control of Open Quantum Systems III: Full counting statistics for jump-based feedback
Alberto J. B. Rosal, Guilherme Fiusa, Patrick P. Potts +1
In this work, we consider a general feedback protocol based on quantum-jump detections, where the last detected jump channel is stored in a memory and subsequently used to implemen…
Framework for fluctuating times and counting observables in stochastic excursions
Guilherme Fiusa, Pedro E. Harunari, Abhaya S. Hegde +1
Many natural systems exhibit dynamics characterized by alternating phases or recurring sets of states. Describing the fluctuations of such systems over stochastic trajectories is n…
Counting observables in stochastic excursions
Guilherme Fiusa, Pedro E. Harunari, Abhaya S. Hegde +1
Understanding fluctuations of observables across stochastic trajectories is essential for various fields of research, from quantum thermal machines to biological motors. We introdu…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Queued quantum collision models
Guilherme Fiusa, Gabriel T. Landi
Collision models describe the sequential interactions of a system with independent ancillas. Motivated by recent advances in neutral atom arrays, in this Letter we investigate a mo…
Fidelity-based distance bounds for -qubit approximate quantum error correction
Guilherme Fiusa, Diogo O. Soares-Pinto, Diego Paiva Pires
The Eastin-Knill theorem is a central result of quantum error correction theory and states that a quantum code cannot correct errors exactly, possess continuous symmetries, and imp…
