Electron pairing in quantum dots as new approach to qubit research qutech.nl/2022/11/23/ele…

🔦 JOB OF THE WEEK: Michael Wimmer answers 5 questions about the job opening for ‘Faculty position for experimental Physics of Quantum Devices’ at QuTech: shorturl.at/pIJ07. Read more on the position here: ap.lc/tBfFK#QDNL #QuantumJoboftheWeek #QDNL

Quite some media attention for our recent publication of QuTech. Check out the paper at nature.com/articles/s4158…

Our paper on Cooper pair splitting in superconductor-semiconductor hybrids is now online: nature.com/articles/s4146… As a follow up we have now been able to controllably tune the interactions between the quantum dots to create localized Majorana bound states...stay tuned for more.

Here is our work on two-site Kitaev chains in 2DEGs: arxiv.org/abs/2311.03208 . What I find so reassuring is that physics works! We see the same phenomena that our colleagues saw earlier this year in nanowires: nature.com/articles/s4158…

....and is now pushed further to make more robust chains: arxiv.org/abs/2311.03193. I'm cautiously optimistic that we could now start doing some really fun physics with Majoranas in these systems.

Very happy to contribute in this amazing team! orangeqs.com/news/qukit_ann…

Our paper on a 2-site Kitaev chain on a two-dimensional platform has now been published. We hope that this is a step towards systematic studies of Majoranas. Congratulations to all, and a special thanks to the entire Kitaev team at Delft. nature.com/articles/s4158…

arxiv.org/abs/2406.06410 Our preprint on the study of local density of states in superconductor-semiconductor hybrids. We made devices to study how the microscopic properties change along the length of a gate-defined hybrid nanowire. Proud of this study, been a long time coming.

Our work on a non-local Josephson effect in multi-terminal junctions is now published. journals.aps.org/prb/abstract/1… Some features often associated with the observation of hybridized Andreev levels can in fact arise from a much simpler treatment of a network of 2-terminal junctions.

🔎 We are looking for a principal investigator to help us build the next generation of quantum technology based on innovative materials. 🤔 Interested in new superconductors, semiconductors or hybrids that may drive the development of qubits? Apply now!👇 qutech.nl/vacancy/group-…

scipost.org/SciPostPhys.17… What happens when you thread flux through a double quantum dot? We use gate-sensing to answer this question.

Our work on a three site Kitaev chain. Interesting to see how we can begin to distinguish between the edge and bulk properties of a system with Majoranas. arxiv.org/abs/2410.00658

arxiv.org/abs/2501.15912 Our latest work shows how semiconductor quantum dots separated by almost a micron can still be effectively coupled via extended Andreev bound states, allowing us to create Kitaev chains.

New Fabrication Engineer position open at QuTech. The position involves hands-on fabrication work on superconductors, semiconductors and hybrid devices. careers.tudelft.nl/job/Delft-Fabr…

There is more than one way to engineer Majoranas. Our latest work on a 3-site Kitaev chains in 2DEGS was just published in Nature: nature.com/articles/s4158… A broad overview here: qutech.nl/2025/04/30/maj…
