Deterministic teleportation using single-photon entanglement as a resource
Gunnar G. Bjork, Amine Laghaout, Ulrik L. Andersen · Physical Review A · 2012
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 nonlinearity, and a two-level atom.
