Gunnar Bj\"ork, Amine Laghaout, Ulrik L. Andersen
TL;DR
This paper demonstrates that single-photon entanglement can be used for reliable deterministic quantum teleportation, challenging skepticism and proposing a practical Bell state analyzer using classical resources.
Contribution
It provides a proof that single-photon entanglement can achieve deterministic teleportation and introduces a classical-resource-based Bell state analyzer.
Findings
Single-photon entanglement can enable reliable deterministic teleportation
Proposed Bell state analyzer uses only classical resources
Dispelled skepticism about single-photon entanglement as a quantum resource
Abstract
We outline a proof that teleportation with a single particle is in principle just as reliable as with two particles. We thereby hope to dispel the skepticism surrounding single-photon entanglement as a valid resource in quantum information. A deterministic Bell state analyzer is proposed which uses only classical resources, namely coherent states, a Kerr non-linearity, and a two-level atom.
