- Abstract: We introduce a generalized concept of quantum teleportation in the framework
of quantum measurement and reversing operation. Our framework makes it possible
to find an optimal protocol for quantum teleportation enabling a faithful
transfer of unknown quantum states with maximum success probability up to the
fundamental limit of the no-cloning theorem. Moreover, an optimized protocol in
this generalized approach allows us to overcome noise in quantum channel beyond
the reach of existing teleportation protocols without requiring extra qubit
resources. Our proposed framework is applicable to multipartite quantum
communications and primitive functionalities in scalable quantum architectures.
