Photon statistics of non-Gaussian entanglement based on two-mode photon-subtracted squeezed vacuum states

荷雨 黄, Hongbin Song, Huayan Wu +4 more

We investigate the photon statistics of two-mode photon-subtracted squeezed vacuum states (TMPSSV), which are important factors to affect the sensitivity and resolution of optical interferometers. The comparison between the photon statistics of TMPSSV and two-mode squeezed vacuum states (TMSV) shows that the non-Gaussian operation has the effect of narrowing the characteristic widths of photon number probability distributions. Different from the super-Poissonian statistical distribution of TMSV, when the initial squeezing parameter is lower, TMPSSV shows a sub-Poissonian statistical distribution which is desirable for enhancing the sensitivity and resolution of interferometers. Therefore, non-Gaussian entanglement based on TMPSSV provides a promising quantum resource for an ultra-sensitivity and super-resolution optical interferometer far beyond the standard quantum limit.

Teleportation of two-mode squeezed vacuum states

Yan We

The teleportation of two-mode continuous variables was performed by using two two-mode squeezed vacuum states served as quantum channel.The average fidelity and the probability density were calculated for teleportation of a two-mode squeezed vacuum state.The results indicate that increased squeezing of teleported state will lead to a loss of fidelity.The probability density of measuring result consists of the product of two bivariate normed density functions,and it shows that when the average fidelity goes up,the probability of obtaining large measurement value also increases.

Calculation of the Quadrature-amplitude Measurement in the Two-mode Squeezed Vacuum State via the Entangled State Representation

Xuefen Xu

Based on the subject proposed in Ref.[4](Acta Sinica Quantum Optica V.8(2002) 47) this paper makes some new profound discussions.It calculates the result of the quadrature-amplitude measurement on the first-mode field of a two-mode squeezed vacuum state via the entangled state representation,and it is shown that the second-mode field collapses to a single-mode squeezed state,whose explicit form is derived.
