Squeezed Light: Noiseless Light
A review on basic theory of squeezing and the nature of quantum noise in optical fields has been presented. Quantum noise, or fluctuation, in light waves limits the precision of measurements. A solution is to make part of a wave quieter by making another part noisier. Few basic applications of squeezed light also have been discussed.
