Welcome to the Groeblacher Lab


In our lab we aim to probe quantum physics on a meso- and macroscopic level using mechanical oscillators coupled to an optical cavity field through radiation pressure. This is a relatively new research field, typically referred to as optomechanics. Over the past few years we have been able to experimentally demonstrate coherent quantum control of macroscopic degrees of freedom. If you want to find out more about this exciting field look at some of our recent publications, at this overview article or at a more detailed description of our research.

Our experiments involve techniques from quantum optics, finite element simulation, cryogenics, RF and high-vacuum technology. We fabricate the mechanical oscillators for our experiments in house at the Kavli Nanolab.

We are located at Delft University of Technology, home to Nobel Laureates Jacobus Henricus van ‘t Hoff and Simon van der Meer, amongst many other great scientists. We are part of the Department of Quantum Nanoscience, as well as the Kavli Institute of Nanoscience.

We are continuously looking for talented and passionate Master students, PhDs, as well as Postdocs. You can find more information here!

We are grateful for funding from Delft University of Technology, the European Research Council, NWO, the Frontiers in Nanoscience program, and the Kavli Foundation.
