Beating the standard quantum limit with single-photon-added coherent states
Pankaj K. Jha, Lakshya Nagpal, Amir Targholizadeh +2
The standard quantum limit (SQL), also known as the shot-noise limit, defines how quantum fluctuations of light constrain measurement precision. In a benchmark experiment using the…
