ERC Starting Grant for Simon!
Simon has been awarded a prestigious Starting Grant by the European Research Council (ERC), the highest award for successful young scientists in Europe. We will receive 2.2 million euros of funding for our research on the interface between the classical and the quantum worlds. See here for the official press release by the University of […]
Minimization of micromotion for nanoparticles in a Paul trap
Our new paper on „Minimization of micromotion for nanoparticles in a Paul trap“ is now on arXiv! In this work, we demonstrate methods for efficient minimization of micromotion for nanoparticles in a Paul trap. The most precise method allows us to nullify the stray field comparable to reported values in trapped-ion experiments. Our method provides […]
NV center spin control in our Paul trap!
We demonstrate for the first time coherent microwave control of NV center spins inside our Paul trap. Here, the NV center spin ensemble is hosted within a CVD-grown clamped diamond. For this achievement we have developed and implemented an in-vacuum microwave feed design that allows for strong microwave field strengths at the trap center, without […]
Welcome to Utku Yigit!
Utku received his bachelor’s degree in physics from the İzmir Institute of Technology. He is now joining our diamond levitation team for his master’s thesis. He will focus on using levitated diamonds to sense magnetic field gradients and investigate spin-cooling techniques. Welcome, Utku!
New record on diamond levitation!
This night we have reached a new record in diamond levitation at the highest vacuum so far! We feedback cool the translational motion of the particle and reach stable levitation at <5×10^-7mbar, only limited by the chamber’s current base pressure. This demonstration represents a significant milestone, as it shows that heating of diamond particlesin high […]
First Diamond Particles Trapped!
We’re excited to announce that we’ve successfully trapped our first diamond particles and observed the characteristic fluorescence spectrum of the embedded NV centers! This marks a significant milestone in our diamond levitation experiments and brings us one step closer to unlocking the full potential of this unique system. We look forward to the next phase […]
Leo submitted his Master’s thesis
Congratulations, Leo! Our master’s student Leo Walz has finalized his thesis with the title „Room Temperature Spin Control in High Temperature High Pressure Nanodiamonds„, where he has implemented full spin control of NV spin ensembles in our nanodiamonds from scratch.
Vacuum Chamber for Diamond Trapping Completed
We’ve finished building our vacuum chamber for diamond levitation experiments! The setup includes a linear Paul trap, high-NA lenses, and a metal target for laser desorption loading of diamond particles. Coming up: mounting of lasers and optical components around the chamber. We’re excited to begin trapping diamonds soon—stay tuned!
Celebrating 20 Years of IQOQI
This week, we’ve been celebrating 20 years of the Institute of Quantum Optics and Quantum Information in Innsbruck. It’s been an incredible week filled with extraordinary scientists from across the world and many truly inspiring discussions.
Group Retreat at Meissner Haus
This year, the Quantum Interfaces group had the pleasure of gathering for a group retreat at the cozy Meissner Haus. We spent three wonderful days filled with physics discussions, fun sports activities, and exciting team games such as building a spaghetti tower.
