PhD student position in Quantum experiments with levitated particles

6 months ago


Gothenburg, Sweden Chalmers tekniska högskola Full time


Do you want to perform quantum experiments with a mesoscopic system? This project is then the ideal fit. The goal 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 our group's expertise in magnetically levitating superconducting microparticles on a chip. The research is placed in the vibrant research environment at Chalmers, encompassing the Quantum Technology Laboratory at the Department MC2 and the Wallenberg Center for Quantum Technology.

About the PhD project, the QTlab and WACQT
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 project is to generate quantum states in the center-of-mass motion of levitated microparticles. We will make this possible by merging magnetic levitation of superconducting microparticles with superconducting quantum circuits. Coupling these two platforms will allow us to reach quantum control over the motion of the levitated particles. Within the project, you will simulate and fabricate your devices and use these for your experiments. You will receive training in all required techniques such that you will get a smooth start for performing your project in our collaborative working environment.

The research project is experimental in nature, supervised by Assoc. Prof. Dr. Witlef Wieczorek and funded by an ERC Consolidator Grant. The Wieczorek group is part of the Quantum Technology Laboratory (QTL) at the Department of Microtechnology and Nanoscience (MC2). The QTL performs cutting edge research in the field of quantum technologies and provides an international, creative and stimulating research environment. The Department MC2 houses a state-of-the-art cleanroom facility for micro- and nanofabrication, which is used by us for device fabrication. The project has ties to the Wallenberg Center for Quantum Technology (WACQT). WACQT at Chalmers encompasses research in quantum computing, quantum transduction, quantum sensing, and quantum foundations with a research base in experiment and theory providing a thriving and internationally leading research environment in the field of quantum technologies.
