retrieved by fitting a model function to data, shows that the system has a white noise equivalent absorption per unit length per square root of bandwidth of 2.310 -13 cm -1 Hz -1/2 , solely 44% above the shot noise limit, and a detection sensitivity of 2.210 -14 cm -1 over 200 s...
In the weak coupling, or weak link limit, we find the thermal current analog of the well-known electronic shot-noise expression.doi:10.1088/0953-8984/20/28/285213PattonKelly RarXivJournal of Physics Condensed Matter
To reach this quantum limit, the output noise of a measurement sys- tem must be dominated by the intrinsic noise of an initial quantum amplifier and not that of a subsequent classi- cal one [3, 4]. This requires that shot noise arising from the flow of current through the quantum ...

The total noise observed in this system is only 2 times higher than the quantum shot-noise limit, which has not been achieved before with a non-cryogenic FRS system. The simplicity and robust- ness of the optical setup and integration of the data acquisition and signal processing electronics ...
atmospheric absorption rapidly degrades any quantum state of light, so that for high-photon loss the optimal strategy is to transmit coherent states of light, which suffer no worse loss than the Beer law for classical optical attenuation, and which provides sensitivity at the shot-noise limit. ...
An improvement in precision beyond the limit set by the vacuum-state or zero-point fluctuations of the electromagnetic field is reported for the detection of amplitude modulation encoded on a weak signal beam. The improvement is achieved by employing the squeezed light from an optical parametric osc...
