Quantum teleportation in Heisenberg chain with magnetic-field gradient under intrinsic decoherence [PDF]
Scientific ReportsOne of the most appealing quantum communication protocols is quantum teleportation, which involves sharing entanglement between the sender and receiver of the quantum state. We address the two-qubit quantum teleportation based on the Heisenberg XYZ chain

Entanglement teleportation along a regenerating hamster-wheel graph state [PDF]
Scientific ReportsWe present an efficient and reusable approach to quantum teleportation that allows cyclic teleportation of a two-qubit graph state around a quantum hamster wheel—a ring of qubits entangled as a one-dimensional line prepared on the 20-qubit Quantinuum H1 ...

Catalytic Quantum Teleportation [PDF]
Physical Review Letters, 2021 In this work, we address fundamental limitations of quantum teleportation-the process of transferring quantum information using classical communication and preshared entanglement. We develop a new teleportation protocol based upon the idea of using ancillary entanglement catalytically, i.e., without depleting it. This protocol is then used to show that

Two-copy Quantum Teleportation. [PDF]
Sci Rep, 2018 AbstractWe investigate two-copy scenario of quantum teleportation based on Bell measurements. The detailed protocol is presented and the general expression of the corresponding optimal teleportation fidelity is derived, which is given by the two-copy fully entangled fraction that is invariant under local unitary transformations.

Does Hawking effect always degrade fidelity of quantum teleportation in Schwarzschild spacetime?
Journal of High Energy Physics, 2023 Previous studies have shown that the Hawking effect always destroys quantum correlations and the fidelity of quantum teleportation in the Schwarzschild black hole.

, 2021 AbstractOne interesting application of entanglement is quantum teleportation, which is a technique for transferring an unknown quantum state from one place to another. In science fiction, teleportation generally involves a machine scanning a person and another machine reassembling the person on the other end.

Quantum Teleportation of Shared Quantum Secret [PDF]
Physical Review Letters, 2020 Quantum teleportation allows to transfer unknown quantum states between distant parties. It is not only a primitive of quantum communications but also an essential task in realization of the quantum networks for promising applications such as quantum cryptography and distributed quantum computation.
