Research in our lab explores the control over mechanical motion – down to the quantum regime. We follow different approaches to pursue this exciting endeavor: 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 vision is to develop, on the one hand, novel quantum devices with hybrid mechanical systems for quantum technologies such as quantum-enhanced sensing. On the other hand, we are interested in fundamental questions such as exploring quantum behavior of macroscopic objects.
Our research is interdisciplinary and brings together methods from quantum optics, quantum information, solid state physics, superconductivity, and photonics. Our group expertise spans the entire research methodology: from device simulation over device fabrication in Chalmers in-house Nanofabrication laboratory to device characterization.
If you are interested in joining our research group as a Master or PhD student or as a PostDoctoral researcher, please have a look here. Currently, we have an opening for a PostDoctoral position in our group. The project is focused on quantum-limited displacement sensing and part of the quantum sensing area of the Wallenberg Center for Quantum Technology (WACQT). Interested? Apply here or contact Witlef.
