Generating spin squeezed state with Mach-Zehnder interferometer
Xia Qi-gu · Chinese Journal of Quantum Electronics · 2014
A scheme for generating spin squeezed state with Mach-Zehnder interferometer was presented and influencing of the phase difference between two interfering paths on spin squeezing parameter was also investigated.It's shown that spin squeezing occurs at the direction normal to mean spin direction and y axis and the spin squeezed state can be effectively generated by adjusting the phase difference between two interfering paths and decreasing the population difference between two interfering paths.
