Sensing with
Quantum Light 2020

Sept. 6th – 9th 2020, Berlin


As a successor to last year’s Workshop on “Sensing with Quantum Light” – SQL19, the Department of Physics and IRIS Adlershof, Humboldt-Universität zu Berlin and the organization commitee are proud to announce the continuation of this Series with the workshop “Sensing with Quantum Light 2020” – SQL20. It will take place as a hybrid- conference (simultaneously online & in real-life near Berlin) from Sunday, Sept. 6th  to  Wednesday, Sept. 9th, 2020.

The ability to prepare, manipulate and measure quantum states of light has seen dramatic advances in the last decades, and has been at the forefront of demonstrating and utilizing phenomena such as such as quantum entanglement, and quantum superposition and squeezed light. They are expected to revolutionize a wide range of fields and to form an important the basis for the so-called “second generation” quantum technologies. The area of quantum sensing is expected to be among the first areas to deliver real-world applications and products.

Sensing with classical light in the form of imaging, microscopy, spectroscopy and interferometric methods has always played an enormous role. Sensing with quantum light aims at utilizing the properties of quantum optical states to overcome classical and technological limitations, for example with respect to resolution or sensitivity or by offering new measurement modalities, for example by linking different wavelength regions.

The workshop aims at covering a broad range of theoretical and experimental aspects of sensing with quantum light, offering for forum for both fundamental aspects and applications.

Topics will include:

  • quantum light for imaging applications
  • spectroscopy with quantum light
  • squeezed light for noise reduction
  • sensing with nonlinear interferometers
  • generation of highly non-degenerate photons
  • high-dimensional entangled states for sensing
  • sensing with quantum light at “extreme” wavelengths
  • new quantum sensing modalities with light

The program of the workshop will consist of invited and regular talks, short talks replacing poster sessions, a panel discussion, as well as as social events. All events will be made available as a suitable online format.

Financially supported by the DFG, 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.
