Internship at University of Innsbruck in Innsbruck, Austria

Host: You will be hosted at the Quantum Interfaces Group at the University of Innsbruck, in Innsbruck, Austria.

Opportunity open to: Master students or PhD candidates active in eligible countries.

Length of the stay: Minimum of three (3) months, to be discussed with host organization


The QIA team at the University of Innsbruck (UIBK) is building up an elementary trapped-ion quantum network with an effective 50 km separation, which will serve as a building block for future metropolitan-scale quantum networks.

To achieve this long-distance quantum channel, we need to integrate quantum frequency conversion within our existing two-node quantum network. In the existing network, we have achieved entanglement over a 520 m fiber link based on entangling trapped ions with 854 nm photons [1]. Quantum frequency conversion will allow us to entangle trapped ions with 1550 nm (telecom) photons, which are compatible with transmission over 50 km of optical fiber. This entanglement at telecom wavelengths has already been implemented at one network node [2] and will now be extended across the network.

The intern will take part in constructing this long-distance network, including tests of quantum frequency conversion and of the indistinguishability of 1550 nm photons from both network nodes.

This is an opportunity to develop familiarity with a wide range of techniques in a quantum physics laboratory, including – trapping ions in ultra-high vacuum, – laser spectroscopy, – coherent control of quantum interfaces between light and matter, – nonlinear optical processes (difference-frequency generation), – writing code for laboratory control and data analysis.

We welcome creative, motivated students who would like to start building the quantum internet!
