Jyun-Yi Li, Xiao-Xu Fang, Ting Zhang, Gelo Noel M. Tabia, He Lu,, Yeong-Cherng Liang

TL;DR
This paper demonstrates that the hidden teleportation power in certain entangled states can be activated beyond classical limits, supported by theoretical analysis and a pioneering experimental proof-of-principle using photon pairs.
Contribution
It extends the concept of activating teleportation power from two-qubit states to higher-dimensional qudits and introduces experimental validation with hybrid entanglement.
Findings
Activation of teleportation power in two-qudit Werner states.
Violation of the reduction criterion in rank-deficient states.
Experimental demonstration using photon pair entanglement.
Abstract
Ideal quantum teleportation transfers an unknown quantum state intact from one party Alice to the other Bob via the use of a maximally entangled state and the communication of classical information. If Alice and Bob do not share entanglement, the maximal average fidelity between the state to be teleported and the state received, according to a classical measure-and-prepare scheme, is upper bounded by a function that is inversely proportional to the Hilbert space dimension. In fact, even if they share entanglement, the so-called teleportation fidelity may still be less than the classical threshold . For two-qubit entangled states, conditioned on a successful local filtering, the teleportation fidelity can always be activated, i.e., boosted beyond . Here, for all dimensions larger than two, we show that the teleportation power hidden in a…
