Designing better quantum circuits with AI
Researchers from the group of theoretical physicist Hans Briegel have collaborated with NVIDIA to develop an AI method that automatically generates efficient quantum circuits, a key bottleneck in making existent quantum computers practically useful.

Quantum spin-off sets new record
The spin-off company ParityQC has implemented the largest quantum Fourier transform ever reported using an IBM quantum computer, thereby setting a new milestone on the path toward the industrial application of quantum computers. The quantum Fourier transform is a cornerstone algorithm with applications in cryptography, financial modeling, and materials science.

About us
The Department of Theoretical Physics is part of the Faculty of Mathematics, Computer Science and Physics at the University of Innsbruck. With over 80 employees our department is one of the largest ones of the University of Innsbruck.
The doctoral college „Atoms, Light and Molecules“ installed in the year 2016 and funded by the Austrian Science Fund FWF serves as a training center for highly qualified and motivated academic talents from the national and international scientific community and we are glad to be part of it. This further intensifies the cooperation among scientists within the Special Research Program BeyondC (SFB F71), which connects theoretical and experimental research groups from Innsbruck and Vienna. The consortium aims to develop and exploit new methods and tools to describe, characterize, validate, and manipulate quantum systems in order to achieve the experimental regime of quantum systems for quantum superiority, the ability of quantum computing devices to solve problems that their classical counterparts cannot. The Department of Theoretical Physics is also part of the Quantum Science Austria (quantA) cluster of excellence, which is further advancing fundamental research in the quantum sciences.
Additionally the technological capabilities have been improved recently by jointly used state-of-the-art facilities.
