Quantum Interfaces Group


The Quantum Interfaces group is led by Prof. Tracy Northup at the University of Innsbruck's Institute for Experimental Physics. In our labs, we investigate how to transfer quantum states between light and matter, based on the interactions between single atoms, photons, and phonons. These fundamental physics experiments have applications for emerging quantum technologies, and in particular, for future quantum networks.



April 03, 2020 Our group has received funding from the Austrian Science Fund (FWF) to develop nodes for trapped-ion quantum networks based on microelectromechanical systems (MEMS), as part of an Austrian research initiative on Quantum Research and Technology (QFTE).

March 09, 2020 Welcome to Jakob Wahl! Jakob has joined the fiber cavity experiment as a master's student. Some of our fiber cavity properties can't be explained using existing mathematical models, and Jakob is developing new models to investigate this question.

February 12, 2020 Tracy was interviewed about the quantum internet on the Nature podcast, which was reporting on entanglement of remote quantum memories in Jian-Wei Pan's group.


November 10, 2019 Welcome to Max Meusburger! Max joined the nanosphere experiment as a master's student. He wants to work on transferring a nanoparticle from a Paul trap to an optical trap.
