Revealing invisible spatial structure of quantum squeezed vacuum
Quantum enhanced measurements depend on generation of squeezed light with quantum fluctuations below standard quantum limit. Precise spatial information about squeezed modes is crucial to reach maximum quantum advantage in sensing applications. Yet the mixed mode squeezed vacuum (the extreme case of squeezed light) is particularly elusive for such characterization. We will present our method, based on the structured light homodyning, to extract squeezing levels and mode shapes from a multimode quantum squeezed vacuum beam.
