Welcome to the Groeblacher Lab

Support for Ukranian students:

If you or someone you know is working on a Masters, PhD, or Postdoc in Ukraine on any subject related to quantum physics, and you would like to continue your research in the coming months, I would like to invite you to join us in the Netherlands. My group will cover your living costs and also travel if possible - no strings attached, and together we will make sure that you can continue working on a relevant topic for your own research. I realize it may be difficult to join us right at this moment given the situation on the ground - just keep our offer in mind and contact me if you’re interested.

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.

We are currently in the process of establishing a national testbed for mechanical sensors, fully funded by Quantum Delta NL. If you are interested to work at the intersection of a startup company and academic research, we have an open position for the Director of the testbed. For more information please click here.

We have successfully started our first spin-off company from the lab - QphoX. Over the coming years, we will be developing the first Quantum Modem device, which will allow to network quantum processors and will form the backbone of the quantum internet. This endeavor is being support by Quantonation, Speedinvest, HTGF and the TU Delft!
