Deterministic quantum master equation for non-Markovian signal processing
Guilherme de Sousa, Diogo O. Soares-Pinto
In this work, we derive a deterministic master equation to model a general, possibly non-Markovian, feedback. The master equation describes a system with a general evolution and me…

Quantum Fokker-Planck Master Equation with general signal filtering
Guilherme de Sousa
In this paper, we derive a general master equation for continuous feedback based on arbitrary linear signals. This result is an extension of the Quantum Fokker-Planck Master Equati…

Continuous feedback protocols for cooling and trapping a quantum harmonic oscillator
Guilherme De Sousa, Pharnam Bakhshinezhad, Björn Annby-Andersson +3
Quantum technologies and experiments often require preparing systems in low-temperature states. Here, we investigate cooling schemes using feedback protocols modeled with a Quantum…
