Optimal continuous-variable teleportation under energy constraint [PDF]
, 2017 Quantum teleportation is one of the crucial protocols in quantum information processing. It is important to accomplish an efficient teleportation under practical conditions, aiming at a higher fidelity desirably using fewer resources.

Quantum teleportation is a reversal of quantum measurement
Physical Review Research, 2021 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 ...

Reordering and Partitioning of Distributed Quantum Circuits
IEEE Access, 2022 A new approach to reduce the teleportation cost and execution time in Distributed Quantum Circuits (DQCs) was proposed in the present paper. DQCs, a well-known solution, have been applied to solve the problem of maintaining a large number of qubits next ...

Operational advantages provided by nonclassical teleportation
Physical Review Research, 2020 The standard benchmark for teleportation is the average fidelity of teleportation and according to this benchmark not all states are useful for teleportation.

Teleportation: from probability distributions to quantum states [PDF]
, 2000 The role of the off-diagonal density matrix elements of the entangled pair is investigated in quantum teleportation of a qbit. The dependence between them and the off-diagonal elements of the teleported density matrix is shown to be linear.

Enhancing quantum teleportation fidelity under decoherence via weak measurement with flips
EPJ Quantum Technology, 2022 Noiseless quantum channels are critical to share a pure maximally entangled state for performing an ideal teleportation protocol. However, in reality the shared entanglement severely degraded due to decoherence.

Teleportation of quantum states [PDF]
Physical Review A, 1994 Bennett et al. (PRL 70, 1859 (1993)) have shown how to transfer ("teleport") an unknown spin quantum state by using prearranged correlated quantum systems and transmission of classical information. I will show how their results can be obtained in the framework of nonlocal measurements proposed by Aharonov and Albert I will generalize the latter to the ...

Estimating entanglement in teleportation experiments [PDF]
, 2018 Quantum state teleportation is a protocol where a shared entangled state is used as a quantum channel to transmit quantum information between distinct locations. Here we consider the task of estimating entanglement in teleportation experiments.

A QUANTUM TELEPORTATION GAME [PDF]
International Journal of Quantum Information, 2005 We investigate a game where a sender (Alice) teleports coherent states to two receivers (Bob and Charlie) through a tripartite Gaussian state. The aim of the receivers is to optimize their teleportation fidelities by means of local operations and classical communications.
