Doctoral student in quantum technology with superconducting circuits

Do you want to explore the generation of quantum states in levitated microparticles and contribute to the development of superconducting quantum technologies? As a Doctoral student in this project, you will perform cutting-edge experiments at the frontier of quantum technology. About Us The Department of Microtechnology and Nanoscience advances the frontiers in quantum technology, nanoscience, photonics and future electronic systems - for technical and societal development. Our cross-disciplinary approach gives interesting collaborations in academy, industry and society, and is a driving force for innovations, results and breakthroughs. We offer a vibrant, international research environment and direct access to world-class nanofabrication facilities. At the Quantum Technology Laboratory, we explore how quantum physics can unlock radically new ways of processing information - far beyond the limits of classical systems. Our research spans quantum computing, sensing, transduction, thermodynamics, and foundations, all aimed at harnessing the powerful behavior of light and matter at the quantum level. We offer a vibrant, international research environment and direct access to world-class nanofabrication facilities. About The Research Project The vision of the project is to explore the generation of quantum states in the center-of-mass motion of levitated microparticles. This research project builds upon the Wieczorek group's expertise in magnetically levitating superconducting microparticles on a chip. Magnetic levitation of superconducting microparticles is a platform that greatly decouples the center-of-mass motion of a levitated mechanical resonator from its environment. This platform will enable ultra-sensitive force and acceleration sensors, as well as quantum experiments with macroscopic objects of 10^13 atomic mass units. The goal of the Doctoral student project is to develop and realize superconducting quantum circuit elements that can efficiently couple to the motion of the levitated particle. Within the project, you will simulate and fabricate your devices and use these for your experiments. You will receive training in all required techniques to ensure a smooth start to your project in our collaborative research environment. The research project is experimental in nature and supervised by Prof. Dr. Witlef Wieczorek. The Wieczorek group is part of the Quantum Technology Laboratory (QTL) at the Department of Microtechnology and Nanoscience (MC2). The project will profit from synergies with the superconducting circuit technology developed within the Wallenberg Center for Quantum Technology.
