Squeezing and Quantum Statistical Property in Two-mode Superposition States
Mu Yi · Journal of Sichuan Normal University · 2003
On the basis of singlemode superposition states, we study further the twomode superposition stats. The squeezing and quantum statistical properties in different twomode superposition states have been studied. The influences of the number photon, number difference, coefficients in the states and their relative phase on these nonclassical properties have been discussed. Finally, the squeezing in the twomode superposition states is compared with that in the singlemode ones. The results indicate that both in twomode singlephoton and twomode twophoton superposition states exists sum squeezing, however, only twomode singlephoton superposition states have normal squeezing.
