The operation of a large-scale ground-based interferometer with Fabry-Perot cavity has evolved in recent years as a result of advances in technology which helps in increasing the sensitivity of the detector, through the use of multiple beam interference in the optical system that is design for detecting gravitational wave signal easily from pulsar and transient source of black holes and neutron stars. The present of quantum noise in the interferometer causes stochastic fluctuations in the arrival time of the photons at the photo-detector and this affect the signal-to-noise ratio, this noise effect can be overcome using different approaches such as variational readout, squeezed light injection, finesse technique.
