Sponsored by BMBF

In the collaborative project "QRydDemo" researchers of the 5th and 3rd Institute of Physics at the University of Stuttgart, the Institute of Complex Quantum Systems at Ulm University and TOPTICA Photonics AG in Gräfeling as a partner from industry want to realize a demonstrator for a Rydberg quantum computer. The consortium is led by Tilman Pfau, 5th Insitute of Physics at University of Stuttgart and IQST Director. For more than 15 years, he has been working with Rydberg atoms, first focusing on pioneering studies of collective many-body phenomena in Rydberg quantum gases, and later on topics ranging from ultralong-range Rydberg molecules, to Rydberg quantum optics in cold and hot vapors. 

The project aims to realize a quantum computer demonstrator with several hundred qubits based on individually controlled Rydberg atoms. In order to reach this goal, Rydberg atoms are grouped in a two dimensional optical trap structure and quantum logical operations are performed by controlled entanglement and shifting the atom traps.

The Federal Ministry of Education and Research (BMBF) supports this project with nine Million Euro, the industry partner contributes another 1.1 Millionen Euro.
Funding period: 01.02.201 - 31.01.2025
