Last chance to join our From Lab to Fab: Quantum Sensing and NV Control Webinar 💡

Tommorrow we will talk about how teams approach engineering for quantum that fits, with a focus on building reliable, modular control stacks, achieving sub nanosecond timing and synchronization, and handling integration challenges in a realistic way.

The discussion brings together experimental and engineering perspectives to help de risk your roadmap and introduce more structure and rigour into NV centres design.

Last week, our CFO Blaž Hrastar had a slightly different meeting on his calendar. 🧸

He visited a kindergarten and explained what we Cosylab do to a group of very curious little ones. There were plenty of interesting questions, some very creative interpretations, and lots of excitement.

They even received Cosylab T-shirts!
To make them a better fit for the youngest audience, we gave our slogan a playful twist. ✨
From Advancing Humanity, Engineering Remarkable to Advancing HuMEOWnity, Engineering ReBARKable.
Take a look at the t-shirt to get the point. 🐾

Moments like these are meaningful to us; when work and everyday life overlap in a simple and genuine way💙

We are just one week away from From Lab to Fab: Quantum Sensing and NV Control Webinar 🚀

Why should you join the webinar?

Across advanced research and sensing platforms, teams often reach a critical point. Promising experiments are in place, but turning them into reliable, modular control stacks that work consistently day after day requires careful integration engineering and structured ex*****on. This webinar will focus on how teams can move beyond exploratory setups toward systems designed for long term operation.

As a sneak peek, one of our speakers, Dr. Izidor Benedičič (from Jožef Stefan Institute), will address a key question in fundamental research:

How can nitrogen vacancy centers advance fundamental research?

In his talk, Izidor will discuss how sensing with color centers enables nanoscale measurements, highlight the practical challenges of using NV centers in condensed matter physics, and demonstrate how nanodiamonds can serve as a probing platform.

Join us and be part of the conversation. 💡

🚀 Interested in work where research and software development directly support patient care?

We are looking for a PhD Student / C # Full-stack Developer to join Cosylab and the RAPTORplus MSCA Doctoral Network, focused on advancing online adaptive particle therapy (OAPT).

🧠 This isn’t just another PhD.
As a PhD student at Cosylab, you’ll combine full-stack software development and research, contributing to adaptive particle therapy workflows for clinical applications. Your work will include algorithm design, backend and database development, and frontend interfaces, in close collaboration with international research and industry partners.

The position includes structured training activities and secondments abroad (Spain, Norway, Switzerland), offering a strong international research experience.

📅 Applications are open until February 8, 2026

Last week, we visited the Faculty of Mathematics and Physics at the University of Ljubljana, where we presented Cosylab, our work and the types of challenges we solve, many of which are closely connected to the Physics Master’s programme.🎓

It was a great opportunity to show how physics knowledge is applied in real-world environments and complex systems beyond academia.

At Cosylab we value strong academic foundations and support students in shaping their professional path. We are always glad to connect and to be part of the academic community today and potentially the professional journeys of the future. 🤝

When experimental setups grow more complex, structured engineering introduces rigour. 💡

Across advanced research and sensing platforms, teams face a familiar challenge: moving from promising experiments to reliable, modular control stacks that work consistently day after day.

To address this, we are hosting a LIVE WEBINAR | on February 4, where we will share real examples of integration engineering and full-stack engineering, from system architecture and firmware; to RF; microwave and DAQ; based on experimental systems developed at Silicon Austria Labs (SAL) and Jozef Stefan Institute.

The session will show how milestone-driven delivery, sub-nanosecond timing and synchronisation, and RFSoC integration helped de-risk experimental roadmaps and improve day-to-day reliability.

German Economic Delegation Visits Cosylab 🇩🇪🤝

On January 5th 2026, we were honored to host an economic delegation from Germany, comprising Tobias Gotthardt, State Secretary, and Stefan Block, Deputy Head of Division, both from the Bavarian Ministry of Economic Affairs, and Her Excellency Julia Kohlheim, Deputy Head of Mission at the German Embassy in Slovenia. We were also joined by Dagmar von Bohnstein, President of the German-Slovene Industry and Trade Chamber (https://bit.ly/4qKBW47) and the Consul General of Slovenia in München, Maša Šiftar.

Cosylab's CEO, Mark Pleško, and the Head of Fusion Domain, Rok Šabjan, presented our strong presence in Bavarian deep-tech initiatives, including Fusion Energy, Quantum and Semiconductors. We explained how we can help overcome the challenges of successfully transitioning from scientific initiatives to industrial projects, based on our rich experience.

Our guests presented the possibilities of deep-tech collaboration with Bavaria and Germany, connecting with strategic partners and discovering mutual shared opportunities, which are enhanced by the existing close geographical and cultural ties between Slovenia and Bavaria. 🚀
