#quantumcontrol — Public Fediverse posts

"Wie sieht die Zukunft der Quantenphysik aus?" Dieser Frage geht detektor.fm im aktuellen Forschungsquartett-Podcast 🎧 mit dem Jülicher Quantenforscher Tommaso Calarco 👨‍💻🎙 nach. Anlässlich des 100. Geburtstags der #Quantenphysik zeichnet der Leiter des Jülicher Instituts für #QuantumControl die Entwicklung dieser faszinierenden Wissenschaft nach, ohne die es digitale Technologien, wie wir sie heute ganz selbstverständlich nutzen, nicht geben würde.

An introductory lecture on "Numerical Methods of Optimal Quantum Control" I gave some time ago finally made it to YouTube: https://www.youtube.com/watch?v=-14ftS4aNxw

#QuantumControl

re-#introduction after moving instances

Hello mathstodon! 👋
We are a computational #quantum #physics group at the Freie Universität Berlin and the Dahlem Center for Complex Quantum Systems.
Our research interests are in the #QuantumControl of atoms, molecules and condensed matter systems with an #AMO like structure as well as #QuantumInformation processing.
We are using both #CoherentControl concepts and #OptimalControl theory, applying them to isolated as well as open quantum systems.
The development of optimal control methods is a major part of our work. A current emphasis is on control methods for open quantum systems.

We collaborate with research groups all over Europe (France, Spain, Switzerland), Israel and the US.

Thanks for having us, we are looking forward to sharing and discussing research updates!

For friends of #QuantumControl and #QuantumTechnologies: Out now in #PRXQuantum, our newest paper.

How do you combine feedback and gradient-based optimization of control strategies --- something that is very useful for optimizing quantum error correction and many other important tasks? "feedback GRAPE" is our answer, as a new technique:

On that note, if you need more performance or flexibility than #Python can provide for #QuantumControl implementations, check out the #JuliaLang code at https://github.com/JuliaQuantumControl

It’s nice to see this paper coming out using our #opensource #python implementation of Krotov’s method for #QuantumControl https://scipost.org/SciPostPhys.13.6.121

I find that my open source work generates more engagement than any other publications. It’s very motivating to find people using tools that you’ve built.

Our paper "Quantum Optimal Control via Semi-Automatic Differentiation" was published in @quantumjournal today.

In this paper, we develop a general method for gradient-based #QuantumControl for arbitrary non-analytical functionals like entanglement measures. This is powered by automatic differentiation (AD) but avoids the exorbitant numerical cost that AD usually has.

The resulting scheme is implemented in #julialang as part of GRAPE.jl / QuantumControl.jl
