Optimal phase sensitivity by quantum squeezing based on a Mach–Zehnder interferometer

Optimal phase sensitivity by quantum squeezing based on a Mach–Zehnder interferometer

A novel scheme for the enhancement of phase sensitivity based on a Mach–Zehnder interferometer (MZI) and intensity detection is proposed. With the input of bright entangled twin beams from four wave mixing (FWM), the phase sensitivity can beat shot noise limit (SNL) and approach Heisenberg limit. Th...
