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 novel quantum devices with hybrid mechanical systems for quantum technologies such as quantum-enhanced sensing. We are also interested in fundamental research 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.
