Abstract

In this letter we analyze the efficacy of the entangled output of Pati-Braunstein (arxiv:quant-ph/0007121v1, 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 α 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 $${({\rm i.e.}\,\frac{2}{3})}$$ .
