Optimal tests for continuous-variable quantum teleportation and photodetectors
Physical Review Research, 2022 Quantum teleportation is a primitive in several important applications, including quantum communication, quantum computation, error correction, and quantum networks. In this paper, we propose an optimal test for the performance of continuous-variable (CV)

Mixedness and teleportation [PDF]
Physical Review A, 2000 We show that on exceeding a certain degree of mixedness (as quantified by the von Neumann entropy), entangled states become useless for teleporatation. By increasing the dimension of the entangled systems, this entropy threshold can be made arbitrarily close to maximal.

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.

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 of quantum coherence
Physical Review A, 2023 We investigate whether it is possible to teleport the coherence of an unknown quantum state from Alice to Bob by communicating a lesser number of classical bits in comparison to what is required for teleporting an unknown quantum state. We find that we cannot achieve perfect teleportation of coherence with one bit of classical communication for an ...

Quantum Reports, 2023 Quantum teleportation is the name of a problem: How can the real-valued parameters encoding the state at Alice’s location make their way to Bob’s location via shared entanglement and only two bits of classical communication? Without an explanation, teleportation appears to be a conjuring trick.

SkyPort: Investigating 3D Teleportation Methods in Virtual Environments
International Conference on Human Factors in Computing Systems, 2022 Teleportation has become the de facto standard of locomotion in Virtual Reality (VR) environments. However, teleportation with parabolic and linear target aiming methods is restricted to horizontal 2D planes and it is unknown how they transfer to the 3D ...

Quantum teleportation with imperfect quantum dots
npj Quantum Information, 2021 Efficient all-photonic quantum teleportation requires fast and deterministic sources of highly indistinguishable and entangled photons. Solid-state-based quantum emitters—notably semiconductor quantum dots—are a promising candidate for the role. However,

Ranking and clustering of nodes in networks with smart teleportation [PDF]
, 2012 Random teleportation is a necessary evil for ranking and clustering directed networks based on random walks. Teleportation enables ergodic solutions, but the solutions must necessarily depend on the exact implementation and parametrization of the ...
