Witlef Wieczorek

Head of Division at Quantum Technology

Witlef Wieczorek is leading a research group that explores the control over mechanical motion down to the quantum regime. The group follows different physical approaches to pursue this research: 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 free-standing two-dimensional materials.
