    "abstract": "We propose a method to refine entanglement via swapping from a pair of\nsqueezed vacuum states by performing the Bell measurement of number sum and\nphase difference. The resultant states are maximally entangled by adjusting the\ntwo squeezing parameters to the same value. We then describe the teleportation\nof number states by using the entangled states prepared in this way.",
