Early life and education

Barz studied mathematics, physics and computer sciences at the Johannes Gutenberg University Mainz.[1] During her undergraduate studies she was an Erasmus Programme student at the KTH Royal Institute of Technology.[1] She earned her PhD in Vienna before moving to the University of Oxford, where she worked in quantum photonics.[2] She was awarded the University of Vienna LaudiMaxima Prize for her dissertation.[1][3] Her research created the means to demonstrate blind computing using entangled photons.[4][5] The photons were generated using a nonlinear crystal, and the entangled photons represent qubits of information.[6] Whilst the sender knows the initial state of entanglement, companies in control of data processing will be unaware, making it impossible to decode the information without destroying it.[6][7] Her work was covered in the New Scientist, as well as on the BBC and NBC.[6][8] In 2013 Barz was awarded the Maria Schaumayer Prize and the Loschmidt Prize.[9][10] During her PhD Barz took part in Falling Walls.[11]

Research and career

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] where she is a Fellow and Board Member of the Center for Integrated Quantum Science and Technology.[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.[2] In 2018 she was awarded a €3.6 million grant to work on quantum technologies involving silicon-based photonics.[19]

She serves on the Strategic Advisory Board of QuantERA, a network of quantum technology researchers.[20]
