Electrical signal analysis for quantum communication

With the funding for the "DeLiQuaT" project in 2026, Prof. Dr Kay-Uwe Giering launched the activities of the Chair of Microsystems Engineering / Mixed-Signal Design in the interdisciplinary field of microelectronics and photonic quantum technologies.

Applications such as quantum communication or quantum computing utilise the laws of quantum mechanics for tap-proof information transmission or problem calculation within a reduced complexity class compared to classical implementation.

In a Saxon consortium with the partners Fraunhofer IIS and ENAS as well as the Technical Universities of Dresden and Chemnitz, the project is investigating relevant components for such setups: quantum dots as deterministic single-photon sources on the one hand and photon-number-resolving single-photon detectors on the other.

The project plans to hire two employees at the HTWD for an initial two-year project period. Specifically, they will be working on the statistical analysis of the electrical signals from single photon detectors with regard to the resolution of the photon number as well as the installation of the components in quantum technology demonstrators, in close collaboration with the Fraunhofer IIS Dresden.
