Dependences of Entanglement Swapping for Continuous Variables on Physical Parameters of Experimental System
Xie Changdee · Acta Sinica Quantum Optica · 2004
According to the criteria of the quantum correlation and the fidelity of quantum teleportation of a coherent state, the dependences of the quality of the entanglement swapping on the detection efficiencies, the transmission efficiencies and the initial correlation parameters are calculated in two cases of gain factor g=1 and g=optimal value, respectively. The results provide the useful references for the designs of the experimental systems.
