Quantum Teleportation and Fidelity of One-mode Squeezing Vacuum State
Yun‐Jie Xia · Acta Sinica Quantum Optica · 2008
Based on the proposal of Braunstein and Kimble,we study the quantum teleportation of one-mode squeezing vacuum state via minimum-correlation mixed state.The results show that the fidelity is low by the entangled mixed states as quantum channel.But with the proposal of adjusting the output field displacement factor's fidelity,we find that it can optimize the fidelity of squeezing state.In a certain reign of coefficients,the fidelity will almost reach to 1.
