The Floquet-Magnus expansion of unbounded operators
Daniel Burgarth, Robin Hillier, Davide Lonigro +1
The Floquet-Magnus expansion is a widely used tool to derive effective descriptions of time-periodic quantum systems by approximating their dynamics with a time-independent Hamilto…
Stability and convergence of dynamical decoupling with finite amplitude control
Daniel Burgarth, Paolo Facchi, Robin Hillier
Dynamical decoupling is a key method to mitigate errors in a quantum mechanical system, and we studied it in a series of papers dealing in particular with the problems arising from…
Control of quantum noise: on the role of dilations
Daniel Burgarth, Paolo Facchi, Robin Hillier
We show that every finite-dimensional quantum system with Markovian (i.e., GKLS-generated) time evolution has an autonomous unitary dilation which can be dynamically decoupled. Sin…
