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 […]
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 our yearly 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.
Spin control in Nanodiamonds

Exciting news from the lab! We’ve made a milestone by successfully controlling the spin state of 1000s of Nitrogen-Vacancy centers inside commercial nanodiamonds at room temperature. This is the first time this has been realized in Innsbruck and is a great final achievement of our master student Leo Walz.
First Master’s student joining the Diamond Experiment

Leo Walz is joining us for an external master’s thesis from the University of Heidelberg. He will be focusing on establishing spin control of Nitrogen-Vacancy center spin ensembles at room temperature.
Carl Zeiss Award for Young Researchers

On Monday evening, I received the Carl Zeiss Award for Young Researchers, which is awarded to outstanding up-coming scientists in optics and photonics by the Ernst Abbe Fund every two years. The ceremony took place at the Deutsches Museum in Munich and it was a pleasure to be honored at such a special location. My […]
Pint of Science 2023

Yesterday, together with Prof. Gerhard Kirchmair, I had the pleasure of speaking at the Pint of Science event in Innsbruck. We had a great time discussing the unique features of quantum mechanics and how they can be used to develop quantum technologies such as the quantum internet. The quantum internet has the potential to revolutionize […]
Entangling ions across Innsbruck’s campus

Trapped ions are a promising platform for the realization of future quantum networks, as they combine high quality local quantum operations with an efficient spin-photon interface for long-distance quantum communication. As a first step towards a real-world quantum network of trapped ions we report now on the demonstration of entanglement generation between two trapped ion […]
How to improve NV center entanglement?

Node-to-node entanglement is the crucial resource in a quantum network and it is therefore of prime importance to have its fidelity and efficiency well under control. In Delft, we have done a rigorous study of entanglement generation between two Nitrogen-Vacancy quantum network nodes and shed light on the influcence of various parameters during entanglement generation.
