Our modern society depends on the efficient processing of information, but conventional electronic data processing is reaching its limits. We need new approaches to store and process large amounts of information. Quantum computing is the promising candidate, and quantum supremacy has already been shown in 2019.
If photons are used as qubits, they have to be controlled, slowed and stored, f.e. in a waveguide or a light-cage. Flavie Davidson-Marquis, a PhD-student in the group of Prof. Oliver Benson, who is a member ofIRIS Adlershof, is investigating a novel light-cage type waveguide: She explores the enhanced light-matter interaction resulting from cohabitation of caesium vapour and a guided field.
IRIS Adlershof supports this research with a fellowship, so Flavie can focus on finalizing the project and getting the results ready for publication.
The Ministry of Science and Culture of the State Niedersachsen, has appointed Professor Caterina Cocchi the W3 professorship "Theoretical Solid State Physics" at the Carl von Ossietzky University in Oldenburg. Ms. Cocchi, who is a member of IRIS Adlershof, will move to her new position in Oldenburg at the beginning of the summer semester 2020. She will keep in touch with Humboldt-Universität as a visiting scientist, as project leader within the CRC 951 “HIOS”, as well as a member of IRIS Adlershof.
We warmly congratulate Ms. Cocchi and wish her every success and all the best for her new position. We look forward to our further fruitful cooperation.
An essential prerequisite for quantum communication and technology is the transmission of quantum information over long distances, but far-reaching and stable networks can only be realized with quantum amplifiers. Dr. Tim Schröder conducts research on such amplifiers with the ERC project QUERP “Quantum Repeater Architectures Based on Quantum Memories and Photonic Encoding” and also attempts to combine complementary technologies from quantum communication: In a hybrid quantum repeater module, two different concepts, such as quantum memory in tin defect centers in diamond, and photonic cluster states are to be brought together.
Dr. Olaf Hohm leads the ERC Consolidation Group “Symmetries and Cosmology”. He‘s developing a computational approach based on string theory, arguably the most promising candidate for a complete theory of quantum gravity. This approach might answer questions relating to the very early history of the Universe, and even test string theory on measurements of background radiation.
IRIS Adlershof welcomes its new members warmly and looks forward to a long and fruitful cooperation.
