Goals of the CZS Center QPhoton

Technologies from quantum physics such as lasers, magnetic resonance imaging and semiconductors are already shaping our lives today. The potential of quantum technologies in the areas of communication, computing, sensor technology and imaging dominate technological debates about the future. In order to be able to use these potentials, transregional platforms are needed to combine different areas of expertise. Photonics is one of the key technologies in the field of quantum science: Photons serve as sensor elements, data transmitters and quantum systems. 

The interconnection of quantum technologies and photonics forms the foundation of the Carl-Zeiss-Stiftung Center QPhoton. By linking the three locations, quantum photonics is advancing from basic research to application. The respective strengths in quantum technologies with atoms, solids, superconducting materials and photons complement each other and also enable the promotion of young scientists in a targeted manner.

The goal is to develop a new generation of imaging and sensor technologies based on quantum science. They should enable higher sensitivities and faster data processing. To this end, research is being conducted across three innovation areas: 

  • Sensor technologies for the control of quantum systems.
    Research and development of highly sensitive sensors
  • Quantum technologies for quantum imaging processes
    Development of initial applications such as quantum microscopy in the field of life sciences, among others. 
  • Quantum-based information processing
    Development of methods for data and signal processing as well as specific photonic hardware for use in quantum computing. 

In addition to research collaborations, the scientists benefit from joint guest lectures, seminars and workshops.Cross-location events and further training opportunities complement the programme.
