This workshop is part of the Thematic Einstein Semester “Mathematics for Quantum Technologies” (Summer 2024) funded by the Cluster of Excellence MATH+ and the Einstein Foundation Berlin. A central objective of the workshop is to promote an exchange between mathematicians, physicists and engineers across disciplines on the subject of optimal control of quantum systems.

Thank You!

Registration (online)

The scientific talks will be streamed online via Zoom. Registered participants will receive the Zoom link shortly before the event via e-mail. Note that all times in the schedule refer to Central European Summer Time (CEST).

The registration deadline has already expired.

Registration (on-site)

Registration is mandatory for on-site participation in the workshop.

Registration deadline: April 30, 2024

The registration period has ended prematurely due to the large number of registrations we have received so far. Unfortunately, we cannot accept any more participants.

Poster Session and Welcome Reception

The poster session will take place on Tuesday afternoon (May 21, start: 4.30 p.m.) in the lobby of the Zuse Institute next to the lecture hall. Please bring your printed poster (DIN A0, format: portrait) and hang it up in the slot with your poster number (see list of posters below) during the lunch break.

Social Event

On Wednesday afternoon (May 22, 2–4 p.m.), we will take part in a guided tour across the historic campus Berlin-Dahlem and gain insights into an exciting period in the history of science. The tour starts at the Harnack Haus at 2 p.m.


Meeting point:
Harnack Haus
Ihnestraße 16–20
D–14195 Berlin


You can choose between two tours

  • Tour A: 100 Years of Science at “Germany‘s Oxford”
  • Tour B: “Science Heaven” Dahlem‘s Nobel Laureates

Both tours are offered with an english speaking guide and will take about 90 minutes. Participants are asked to distribute equally between the tours.


The tutorial will give you a chance to explore numerical quantum dynamics and optimal control through a series of Jupyter notebooks. It will cover basic concepts of light-matter-interaction, tuning control parameters with gradient-free methods, all the way to the optimization of entangling quantum gates with Krotov’s method and GRAPE. There will be examples from a variety of physical systems and at different levels of complexity. Thus, different parts of the tutorial will be suitable for students first dipping their toes into numerical quantum control as well as seasoned researchers wanting to get familiar with some of the latest cutting-edge tools.

We will offer versions of the notebooks in Python and the Julia language. For the most part, these will cover the same material, although Julia will allow to explore more advanced topics, like a comparison of GRAPE and Krotov’s method, larger quantum systems, and modern methods such as automatic differentiation.

For Python, the main packages that will be explored are

  • QuTiP – Quantum Toolbox in Python.
  • krotov – An implementation of Krotov’s method built on top of QuTiP 4.
  • NLopt – A nonlinear optimization package.

For Julia, the main packages are:

Parts of the tutorial will be self-directed, depending on your interests and level of experience. You will be running it on your own laptop. The notebooks and detailed installation instructions will be made available before the workshop.

The notebooks for the tutorial are available on GitLab and can be accessed at

The tutorial is planned and conducted by Michael Goerz.

Workshop Dinner

We will visit the restaurant Luise Dahlem on Thursday evening (May 23, from 6:30 p.m.). Information on the coverage of costs will be communicated by the organizers during the workshop.


The workshop will take place in the Lecture Hall of the Zuse Institute Berlin (ZIB).
