Comment to Frequency independent squeezing measurement (6.5dB is achieved) (Click here to view original report: 2382)

We made further anti-squeezing and squeezing measurement. This measurement indicates optical losses to be 19.1%, phase noise to be 20.5mrad.

Therefore, we still have 3% optical losses which are not known.

The ideal sqz-asqz for current set-up and improved set-up are shown as well.
