Heisenberg Picture Approach to the Stability of Quantum Markov Systems
Yu Pan, Hadis Amini, Zibo Miao +3
Quantum Markovian systems, modeled as unitary dilations in the quantum stochastic calculus of Hudson and Parthasarathy, have become standard in current quantum technological applic…
Design of coherent quantum observers for linear quantum systems
Shanon L. Vuglar, Hadis Amini
Quantum versions of control problems are often more difficult than their classical counterparts because of the additional constraints imposed by quantum dynamics. For example, the…
Stability of continuous-time quantum filters with measurement imperfections
Hadis Amini, Clement Pellegrini, Pierre Rouchon
The fidelity between the state of a continuously observed quantum system and the state of its associated quantum filter, is shown to be always a submartingale. The observed system…
Feedback stabilization of discrete-time quantum systems subject to non-demolition measurements with imperfections and delays
Hadis Amini, Abhinav Somaraju, Igor Dotsenko +3
We consider a controlled quantum system whose finite dimensional state is governed by a discrete-time nonlinear Markov process. In open-loop, the measurements are assumed to be qua…
Real-time quantum feedback prepares and stabilizes photon number states
Clément Sayrin, Igor Dotsenko, Xingxing Zhou +9
Feedback loops are at the heart of most classical control procedures. A controller compares the signal measured by a sensor with the target value. It adjusts then an actuator in or…
On stability of continuous-time quantum-filters
Hadis Amini, Mazyar Mirrahimi, Pierre Rouchon
We prove that the fidelity between the quantum state governed by a continuous time stochastic master equation driven by a Wiener process and its associated quantum-filter state is…
