Abstract:
Abstract: We researched the photon distribution of de- Gaussian two- mode squeezed vacuum field,analyzed
the transferred entanglement between the field and Qubits based on J- C model,characterize entanglement by loga-
rithmic negativity. The results show that the photon- subtracted field can achieve high entanglement at lower squee-
zing degree,photon distribution will change to Bell- basis with subtracting photon and enhance the transferred entan-
glement; the photon- added ones will be Bell- basis when squeezing degree is 0,and the entanglement can be com-
pletely transferred.
