The vision of our lab is to explore the quantum behavior of macroscopic objects and to develop novel quantum sensing technologies.

We address these research questions with nano- and micromechanical systems. The key in our research is that we follow different approaches to pursue our exciting research activities: coupling mechanical motion to light in so-called cavity optomechanical devices; using superconducting magnetic levitation as a means to reach ultra-low mechanical dissipation; and exploring embedded quantum emitters in two-dimensional materials.

Our research is interdisciplinary and brings together methods from quantum optics, quantum information, solid-state physics, superconductivity, and photonics. Our group’s expertise spans the entire research methodology: from device simulation over device fabrication in Chalmers in-house Nanofabrication laboratory to device characterization, and, of course, experiments.

Do you want to be part of our exciting journey to observe the quantum behavior of macroscopic objects or to develop novel quantum sensing technologies? We are happy to talk with you! Simply get in touch with us for more in-depth information and a lab tour. Please have a look here. We offer Master thesis projects in our lab. Examples you can find here.

We will have new openings in the fall of 2023 for PhD/PostDoc positions in the field of macroscopic quantum behavior. These positions will be part of an ERC Consolidator Grant. If you are interested to join us, please contact Witlef.
