Start of the Dip-QT Project of QVLS-iLabs

Quantum technologies are subject to a continuously growing demand in high-degree integration of photonic platforms. The works under the Zukunftsclusters QVLS-iLabs bring leading expertise from industry and research together with the following goals: processes for scalable, highly efficient optical connections in an ultra high vacuum and at cryogenic temperatures will be established. Optimized nanostructures and processes for the alignment and fixation of fiber arrays will be developed, in order to ensure stable and efficient optical connections for applications in those vacuums and at those temperatures.

These works will then feed into the setup of two demonstrators: on one hand, a fully integrated, quantum photonic semiconductor system for the application in quantum computing and communication over large distances. This will feature the efficient and stable coupling of active and passive optical elements as well as semiconductor-based quantum chips. On the other hand, a highly compact spectroscopy module will be developed and used as a portable, long-time stable frequency reference for scalable application in optical clocks and quantum computers based on trapped ions, as well as in quantum inertial sensors with neutral atoms in optical potentials. Together with the partners in the QVLS-iLabs project, all central aspects of demand in quantum technologies will therefore be served.
The QVLS-iLabs cluster is one of seven clusters that is being funded through Clusters4Future by the German Ministry of Education and Research.
