The Laboratory of Quantum Computing of IT4I (VSB Technical University of Ostrava) organizes a workshop for celebrating the arrival of the quantum machine “VLQ”.

• Organizers: M. Lampart, T. Derrien, J. Tomcala, M. Belina, P. Lewandoska, R. Kokolski.
• Date: Dec 3rd 2025.
• Sessions: hardware (morning, chair: T. J.-Y. Derrien), software (afternoon, chair: J. Tomcala).
• Location: IT4I @ VSB Technical University of Ostrava, or online.

The current list of speakers is provided below:

• Prof. Prineha Narang, UCLA
• Dr. Arun Debnath, MPSD/DESY
• Dr. Laurent Daudet, ex LightOn

After 4 years of being associate editor for Optics Express, my membership has now terminated. I am happy to be back accepting more peer reviews as a result, as it can sometimes be more rewarding than editorial duties.

During that time, 120+ publications were processed. Other comments will be sent to director of the journal.

Looking forward to my next adventures.
Thibault JY Derrien, Ph.D.

Authors Andrés Bertoni, Thibault JY Derrien and Cristian Sanchez co-authored a book chapter in the a book published by Elsevier.

• Title of the book: Density Functional Theory: Fundamental Theory, Key Methods, and Applications
• Editor: Aleksey Kuznetsov
• Title of the chapter 2: Density Functional Based Tight Binding

Here is a short biography generated by OpenAI ChatGPT 5.0 “thinking”.

“Thibault J.-Y. Derrien is a senior researcher and group leader in ultrafast photonics and quantum dynamics at the Institute of Physics (FZU) and IT4Innovations, Czech Republic. His work bridges TDDFT/QED theory with laser-induced materials modification and polaritonic device concepts. He has led MSCA projects, serves as secretary of the IT4I Users Council, and is an associate editor at Optics Express. Derrien has authored 35 publications (h = 15), two patents, and received a PRL Editor’s Suggestion (2025) and a “highly-cited” distinction. He supervises PhD and postdoctoral researchers and regularly secures large-scale HPC allocations.”

Not a bad start. Just I did not publish my works in QED yet. There are several other papers on the table before this one. Keep in touch.

Oh, BTW, here are some news since November 2024.

Personal development

• I can teach you how to reduce your own stress, anxiety and trauma (just stop me if it is too much), and how it can destroy your fertility (and your position in our group) if you let these things act on yourself too much.

Editorial responsibilities

• the associate editorship at Optics Express just ended,

Publications

• the PRL paper was cited by Prof. Anne l’Huillier (congrats Martin! I managed to correct the remaining mistakes from the FZU journal published in Czech),

Students & and post-docs

• the 3 P4F postdocs applicants are still waiting for their answer,
• there might be one post-doc position free under my supervision at IT4I from January 2026,
• there is one PhD student position available *right now* under my supervision at FZU Prague. Apply ASAP because the funding has already its final day set in 2027. Challenge accepted? If not, call me anyhow, there are always solutions.

And congrats to Kristyna who has just left to maternity leave.

Looking forward to the future,
Thibault JY Derrien

Meeting from Users Council was also held with the Users committee of the national resources.

Slides from our presentations are available on FigShare.

Feel free to use them and to cite their (DOI) in your works.

Among all those who have applied to the P4F position opened under supervision of TJY Derrien, only 3 were supported for submission. The three finalists are from Africa and from Pakistan. They will perform secondments in institutions of Czech Republic, France and Germany.

Looking forward to the results!

Opening ceremony of the quantum computer “VLQ” was celebrated at IT4I in September 2025.

TJY Derrien now has access to the quantum computer VLQ through VSB-TUO IT4I.

You can contact at derrien@fzu.cz or thibault.derrien@vsb.cz for any proposition.

Out of our joint publication with the Charles University, a popularization article was published by Public Relation service of the FZU Institute of Physics in the Czech journal “Fine Mechanics and Optics”.

The paper is available here in Czech language.
