Deletion, Bell’s inequality, teleportation. (English) Zbl 1209.81044

Summary: We analyze the efficacy of the entangled output of A. K. Pati and S. L. Braunstein [arXiv:quant-ph/0007121 (2000)] deletion machine as a teleportation channel. We analyze the possibility of it violating the Bell’s inequality. Interestingly we find that for all values of the input parameter \(\alpha \) the state does not violate the Bell’s inequality but when used as a teleportation channel can give a fidelity higher than the classical optimum (i.e., \(\frac{2}{3}\)).
