Stefanie Barz is a German physicist and Professor of Quantum Information and Technology at the University of Stuttgart working in the field of photonic quantum technology.[1]

Early life and education

[edit]

Barz studied mathematics, physics and computer sciences at the Johannes Gutenberg University Mainz.[2] During her undergraduate studies she was an Erasmus Programme student at the KTH Royal Institute of Technology.[2] She earned her PhD from the University of Vienna under the supervision of Anton Zeilinger, working on blind quantum computing using entangled photons, where the sender knows the initial state of entanglement, while companies in control of data processing will be unaware, making it impossible to decode the information without destroying it.[3][4][5][5][6] For her dissertation she was awarded the LaudiMaxima Prize[2][7] and her work was covered in the New Scientist, as well as on the BBC and NBC.[5][8] In 2013 Barz was awarded the Maria Schaumayer Prize[9] and the Loschmidt Prize[10]. During her PhD Barz took part in Falling Walls.[11]

Research and career

[edit]

In 2014 Barz was awarded a Marie Skłodowska-Curie Fellowship to work on quantum optics at the University of Oxford. She worked with Ian Walmsley on three photon interference, which could be used for quantum cryptography.[12][13][14] She secured her own funding to work on the project, Secure information processing in quantum networks (seQureNet). During the project she created integrated photon sources, fibre components and waveguide circuits.[15]

She was appointed to the University of Stuttgart in 2017,[16]. Since 2022 she is Director of the Center for Integrated Quantum Science and Technology (IQST), the joint quantum centre of the Universities of Stuttgart, Ulm, and the Max Planck Institute for Solid State Research.[17] Barz works on encrypted cloud computing and photonics.[18] She uses light as a way to demonstrate the power of quantum information. This could make computers faster and more secure.[19] In 2018 she was awarded a €3.6 million grant to work on quantum technologies involving silicon-based photonics.[20]

She serves on the Strategic Advisory Board of QuantERA, a network of quantum technology researchers.[21]

In January 2024 she has been awarded an honorary professorship by the Vienna University of Technology "for her research in the field of photonic quantum technologies".[22]
