Workshop "Sensing with Quantum Light" 2019

As a successor to last year’s Autumn School on Quantum Enhanced Imaging and Spectroscopy, Fraunhofer IOF and IPM and the Institute of Physics, Humboldt University, are proud to announce a Workshop on "Sensing with Quantum Light", which will take place from Sunday, Sept. 15th to Wednesday 18th, 2019, at the Physikzentrum Bad Honnef.

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. Sensing with quantum light aims at utilizing the properties of quantum optical states to overcome classical limitations, for example with respect to resolution and sensitivity. In addition, it is expected to offer the potential for new measurement modalities, for example by linking different wavelength regions.

The workshop will cover theoretical and experimental aspects of sensing with quantum light. Topics will include modalities like sensing with undetected photons via nonlinear interferometers, induced coherence without stimulated emission, spectroscopy with entangled light, the generation of highly non-degenerate photons, ghost imaging and their application potential.

The program of the workshop will consist of invited talks and poster sessions with contributed papers.

Financially supported by the Fraunhofer Gesellschaft through its Lighthouse project QUILT, the workshop aims at providing a vibrant forum for the exchange of ideas and discussion 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 venue of the meeting, the Physikzentrum Bad Honnef, has been chosen because of its proven quality to provide a perfect environment for scientific meetings.
