Minimizing Control Attention:The Linear Gauss-Markov paradigm
Ralph Sabbagh, Asmaa Eldesoukey, Mahmoud Abdelgalil +1
We revisit the concept of `attention' as a technical term to quantify the effort in calibrating control action based on available data. While Wiener, in his work on Cybernetics, an…
On a time-resolved interpretation of the Husimi function
Ralph Sabbagh, Olga Movilla Miangolarra, Tryphon T. Georgiou
In this Letter, we interpret the Husimi function as the conditional probability density of continuously measuring a stream of constant position and momentum outcomes, indefinitely.…
Regulation of a continuously monitored quantum harmonic oscillator with inefficient detectors
Ralph Sabbagh, Olga Movilla Miangolarra, Tryphon T. Georgiou
We study the control problem of regulating the purity of a quantum harmonic oscillator in a Gaussian state via weak measurements. Specifically, we assume time-invariant Hamiltonian…
Quantum Schrodinger bridges: large deviations and time-symmetric ensembles
Olga Movilla Miangolarra, Ralph Sabbagh, Tryphon T. Georgiou
Quantum counterparts of Schrodinger's classical bridge problem have been around for the better part of half a century. During that time, several quantum approaches to this multifac…
