Overcoming the Challenges of Quantum Decoherence in Ultra-Precise Sensing

27 October 2023

Quantum decoherence has long been a significant barrier to achieving the highest levels of sensitivity in ultra-precise force sensors. In our latest experiment, we discovered that generating quantum squeezed light directly within the sensor can substantially mitigate the effects of decoherence. Moreover, we've established a new fundamental quantum limit for such measurements. This work paves the way for more precise and versatile sensors in various scientific and technological applications.

Our work is now published in Physical Review Letters Vol. 113 Issue 14.

Laser Scanning Microscopy for Tomographic Imaging of Roughness and Point Absorbers in Optical Surfaces

High-precision laser interferometric instruments require optical surfaces with a close to perfect contour, as well as low scattering and absorption. Especially, point absorbers are problematic because they heat up and locally deform the otherwise flat surface, resulting in correlations between...
