During the project she created integrated photon sources, fibre components and waveguide circuits. She was appointed to the

in 2017, where she is a Fellow and Board Member of the Center for Integrated Quantum Science and Technology. Barz works on encrypted cloud computing and photonics. She uses light as a way to demonstrate the power of quantum information. This could make computers faster and more secure. In 2018 she was awarded a €3.6 million grant to work on quantum technologies involving silicon-based photonics. She serves on the Strategic Advisory Board of QuantERA, a network of quantum technology researchers.
