Weronika Golletz

PhD student in theoretical physics (time crystals)
Developing Quantum Computing Skills
Aspiring Deep Learning enginner

I am a PhD student in theoretical physics in Krzysztof Sacha's group at the Jagiellonian University in Kraków, Poland. We are working on discrete time crystals made from made from ultra-cold atoms bouncing on an oscillating mirror. We analyze their stability against experimental imperfections and quantum fluctuations.
I am also a @Womanium Quantum Solutions Launchpad Fellow, working on Development of Novel Quantum Algorithms in collaboration with Womanium's partner Classiq (Sep 2024 - Jan 2025). Additionally, I am a participant in the QClass24/25 by QWorld.
July 2023, I completed postgraduate studies in Deep Neural Networks for Digital Media at the Warsaw University of Technology, Poland.
