Germany / Cologne – Netherlands / Dordrecht – Belgium / Antwerpen – Netherlands / Nijmegen – Germany / Cologne

The “Sensing with Quantum Light“ conference series will continue with SQL26 in its now seventh iteration! This time, we are back on the river cruise ship MS Swiss Crown which will start from Cologne and travel through the Netherlands, Belgium and back again. With 4 nights on board and 3 full days scientific program there will be plenty of time for scientific talks, poster sessions as well as informal discussions – all with a view of the beautiful Rhein and opportunities for small excursions along the way.
The workshop again exclusively aims at research involving both: a motivation in quantum sensing and the use of quantum light. Within that domain it will cover a range of theoretical and experimental aspects of sensing with quantum light, offering a vivid forum for both fundamental aspects and applications.
Quantum sensing as such is considered one of the most promising areas of quantum technology in which real-world applications and products are expected soon. Sensing with light in the form of imaging, microscopy, spectroscopy, or other interferometric methods has always played an enormous role in science and technology for more than a century. In recent decades, the ability to prepare, manipulate, and measure quantum states of light has made enormous progress, both in fundamental and technological terms and provides the basis sensing approaches with photonic quantum states (“Sensing with Quantum Light”).
With this focus, the seminar will provide a forum for the exchange of the latest research results, and for the exchange of ideas and discussions by bringing together established scientists from leading research groups in the field, junior scientists and graduate students – with participants from fundamental and applied physics and also industry.
Specific topics will include (but not be limited to):
– advances in quantum light detection
– quantum light astronomy
– squeezed light for noise reduction
– spectroscopy with quantum light
– quantum optics with frequency-combs
– fundamentals of nonlinear interferometers
– high-dimensional entangled states for sensing
– entangled two-photon absorption
– sensing with quantum light at “extreme” wavelengths
– artificial intelligence boosted quantum sensing
– new quantum sensing modalities with light
The program of the workshop will consist of contributed and invited talks, poster sessions as well as social events. Applications will start in Feb. 2026.
