Summary
| Description |
English: Plot of the achieved amount of squeezing of optical light in published laboratory experiments vs the year of publication. The amount of squeezing is given in logarithmic units of dB. Values are the ones from raw measurements without correction for detection losses. This graphic may be updated by anyone using the code below, if data are missing or new data become available. |
