Contrary to what is often stated, the phase space trajectory of a quantum system can be measured with any degree of precision. However, an entangled reference system is necessary. In our work we show experimental results

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...
