A photodetector converts light into an electrical signal, causing the light to be lost. Researchers led by Tracy Northup at the University of Innsbruck have now built a quantum sensor that can measure light particles non-destructively. It can be used to further investigate the quantum properties of light.

Quantum physicist Rainer Blatt has been elected foreign associate of the American National Academy of Sciences. This honour has so far only been conferred on very few Austrian scientists. With Rainer Blatt and Peter Zoller, two physicists from Innsbruck are now represented in this renowned institution.

Die Innsbrucker Quantenphysiker Rainer Blatt und Peter Zoller werden mit dem Micius-Preis ausgezeichnet, der heuer zum ersten Mal verliehen wird. Mit Anton Zeilinger, Ignacio Cirac und Jian-Wei Pan erhalten drei weitere Forscher den Preis, die früher an der Universität Innsbruck tätig waren.

In collaboration with researchers in the group of Peter Zoller, and with the IQOQI Innsbruck, researchers in our group have presented and experimentally demonstrated a protocol to determine the purity and entanglement in many-particle systems. The results, published in Science, demonstrate a universal tool for characterising engineered quantum systems in the lab in greater detail than ever before.

Congratulations, Konstantin!

Thesis Tile: On dispersive interactions between a trapped ion and a cavity field

Marco joined the group as a PhD student. He got his master degree in Photonics and Nano-Optics at Politecnico di Milano and did his master thesis at ICFO in Barcelona working on solid state quantum memories. In Innsbruck he will join the CryoTrap team to work on the development of 2D ion traps.

Max joined our goup. Max got his PhD from the University of Mainz on Measurement of Reduced Dipole Matrix Elements in 40Ca+ and Construction of a Scalable Light-Ion Interface. He will work at Alpine Quantum Technologies on building a quantum computer.

Georg joined our goup. Georg got his PhD from the University of Mainz on Ion Implantation and Transmission Microscopy with Nanometer Resolution using a Deterministic Ion Source. He will work at Alpine Quantum Technologies on building a quantum computer.
