David Sauerwein

David Sauerwein, PhD

David worked on entanglement in quantum many-body systems in the group of Prof.a Barbara Kraus. He quantified and investigated new transformations of multipartite entanglement. During his PhD studies, he visited Gilad Gour at University of Calgary in Canada and he worked with the research group of Ignacio Cirac at MPQ Garching in Germany. He received his PhD in Innsbruck on Feb.19th 2019.

Current employment: Data Scientist, Faculty.ai, London/UK

David Plankensteiner, PhD

David worked on on quantum optics and cavity QED in the group of Prof. Helmut Ritsch. He worked in the field of quantum optics with dipole-dipole interaction of quantum emitters. During his PhD studies, he visited JILA Institute - University of Colorado, Boulder, US, Max Planck Insitute for Science and Light, DE and ICFO - The Barcelona Institute of Science and Technology, ES. He received his PhD in Innsbruck on July 8th 2019.

Davide Orsucci, PhD

Davide worked on quantum algorithms in the theory group of Prof. Hans J. Briegel. For example, he published two quantum algorithms to solve systems of linear equations. During his PhD studies, he visited the Center for Quantum Information and Control in Albuquerque and the Singapore University of Technology and Design. He received his PhD in Innsbruck on October 30th 2019.
