Analytical construction of two-mode squeezed vacuum states with two tunable parameters

Gang Ren, Hai-jun Yu, Chunzao Zhang

We theoretically construct a two-parameter two-mode squeezing operator by combining the two-mode coupled harmonic oscillator Hamiltonian with beam splitter transformations. A novel two-mode squeezed vacuum state (NTMSVS) is generated via the application of this operator to the two-mode vacuum state. Numerical investigations demonstrate that the NTMSVS exhibits intermediate properties between the conventional two-mode squeezed vacuum state (TMSVS) and the product state of two independent single-mode squeezed vacua across multiple quantum metrics, including Wigner distribution characteristics, logarithmic negativity, EPR steering robustness and Bell inequality violation. Notably, the quadrature squeezing and sum squeezing amplitudes are significantly amplified under specific parametric regimes, offering enhanced nonclassicality compared to standard squeezed states.

Entanglement Diversion of Entangled Squeezed Vacuum State

Naosheng Qiao

By analyzing the action of a beam splitter on squeezed vacuum states (SVSs), it is found that, if the two input light beams of the beam splitter have the same squeezing amplitude and phase, the output state is a two-mode SVS. If the two input light beams of the beam splitter have the same squeezing amplitude but a phase difference of π, the output state is a direct product state of two single-mode SVSs. In the two-mode SVS, each mode has the same photon number with both even and odd photons, while the single-mode SVS which contains only even-number photon in the photon number-state representation. Based on these results, a scheme to divert the entanglement of entangled SVS from its initial locations to another location is suggested. In this scheme, the two SVSs are utilized as the quantum channel. The process of the entanglement diversion is achieved by using the 50/50 symmetric beam splitters and the photon detectors with the help of classical information.
