| Abstract: | Single-particle entanglement refers to entanglement produced with a single particle. It can be generated by illuminating a beam splitter with a single photon. We describe experimental schemes to realize quantum teleportation and quantum key distribution utilizing single-particle entanglement, and discuss the strengths and drawbacks of the schemes compared with the standard scheme utilizing two-photon polarization states. We show, in particular, that the quantum key distribution scheme based on single-particle entanglement is associated with a relatively high value of the bits of information transferred per particle sent and can thus be cost effective. |
