Experimental certification for nonclassical teleportation

Abstract

How to properly certify the quantum function of a quantum process (device) is one of the key problems in quantum information science, particularly, for a function beyond its classical counterpart. To properly verify quantum teleportation is a critical task because of its fundamental roles in quantum communication and quantum computation. Here, we experimentally certified nonclassical quantum teleportation with one setting by the random teleportation robustness introduced by [Phys. Rev. Lett. 119, 110501 (2017)]. Our results show that the random teleportation robustness is experimentally convenient and powerful for verifying nonclassical teleportation and entanglement.
