Zusammenfassung:
Here, we report on the generation of strongly squeezed vacuum states at 532
nm with 5.5 dB noise suppression by means of frequency up-conversion from the
telecommunication wavelength of 1550 nm. In addition, we report on the sub-shot
noise sensitivity of a Mach-Zehnder interferometer at 532 nm and therefore,
which is the first demonstration of practicability of frequency up-converted
squeezed states in quantum metrology.
