In the last two decades, the ability to prepare and manipulate quantum states at the individual level has led to a wide range of scientific activities. It is expected that the laws of quantum mechanics with phenomena such as quantum entanglement and quantum superposition will revolutionize a wide range of fields, now frequently coined the so-called “second generation” quantum technologies.

The area of quantum sensing is considered to be one which most likely is going to deliver real-world applications and products soon. Sensing with light in the form of imaging, microscopy, spectroscopy or other interferometric methods has always played an enormous role. As an example, quantum imaging aims at utilizing the properties of quantum optical states to overcome the limits of classical imaging.

This seminar will cover theoretical and experimental aspects of sensing with quantum light. Topics will include modalities like sensing with undetected photons via nonlinear interferometers, sensing with squeezed light, induced, spectroscopy with entangled light, the generation of highly non-degenerate photon, high-dimensionally entangled light and their application potential for sensing tasks.

By bringing together established scientists from leading research groups in the field, junior scientists and graduate students, participants from fundamental and applied physics and industry the seminar aims at providing a vibrant forum for the exchange of ideas and discussion.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
