Researchers within IQST investigate and explore a large range of quantum systems. They seek to gain new understanding of quantum materials, albeit in solid state, biological, or atomic gas systems. They utilize single quantum particles such as on-demand single photons, a single Rydberg atom, or an NV diamond center in order to build up complex quantum systems, investigate light-matter interfaces, study exotic properties of quantum materials, or create ground-breaking new sensors. The foundation of this work is the quantum electrical and optical engineering research within the center; this enables not only the possibility to realize new prototypes of quantum technologies, but also to develop exotic new quantum systems.
Quantum mechanics ultimately limits measurement precision. Exploiting the quantum properties of entanglement and coherence, local quantities such as mass, current and charge can be measured with a sensitivity much improved over classical schemes of sensing.
Complex Quantum Systems
A key challenge in experimental Quantum science is to identify isolated quantum mechanical systems that can be manipulated and coupled in a scalable fashion, but at the same time display good coherence properties.
Tailored Quantum States of Matter
The interplay between interactions and quantum fluctuations is at the very heart of quantum phase transitions and strongly correlated quantum phases. The main goal of this research area is to engineer and develop systems exhibiting novel states of matter such as spin liquid phases or topological phases.
Quantum Electrical and Optical Engineering
In order to integrate quantum systems into larger networks and prototype quantum technologies that maintain coherence of the internal quantum system, the need for a dedicated Quantum Electrical and Optical Engineering becomes obvious.
