Ana Predojević's research team participated in the QuanTour and celebrates the Year of Quantum
2025 is UNESCO's International Year of Quantum Science, and as part of this initiative, a quantum light source was taken on a 12-month tour to 12 institutes in Europe. "We participated in the QuanTour project and conducted experiments on the quantum dot source in February,” said Ana Predojević and her research team at the Department of Physics.

Ana Predojević became interested in physics in elementary school and knew from the beginning that this was what she wanted to do.
"I studied physics and mathematics at a school with a STEM-oriented curriculum in Novi Sad, Serbia, where I also graduated in physics in 2003. Then I was a Ph.D. student at ICFO in Barcelona, where I graduated in 2009. I worked as a postdoc in Innsbruck, where I received my habilitation. In 2015, I was appointed as a professor at the University of Ulm and in 2017 I joined the Department of Physics as an assistant professor. Today, I am an associate professor in the Condensed Matter and Quantum Optics Division and my research group is working on the generation of quantum light, exploiting its unique properties and bringing it closer to applications.”
The Physics Department received the QuanTour quantum dot sample on February 3 and conducted experiments on it until February 20, when it was sent to University of Wrocław, Poland.

"We measured the key performance indicators of the quantum dot device we received and determined how efficiently it worked, and we obtained a set of data that we can now compare with the data from the other universities.” says Ana Predojević.
In this way, the QuanTour is reminiscent of the Olympic flame being sent from country to country. This coincides with UNESCO's International Year of Quantum Science.
Semiconductor devices and non-linear processes can generate a wide spectrum of quantum states of light that can be employed in tasks of communication, simulation, and sensing. We use best tools and methods available to modern science to generate quantum light, harness its unique properties, and bring it closer to real-world application.
