The entanglement is produced by elastic tunneling events, without requiring electron-electron interactions. Here we investigate the inverse process, the annihilation of an electron and a hole by elastic scattering. We find that this process leads to teleportation of the (unknown) state of the annihilated electron to a second, distant electron -- if the latter was previously entangled with the annihilated hole. We propose an experiment, involving low-frequency noise measurements on a two-dimensional electron gas in a high magnetic field, to detect teleportation of electrons and holes in the two lowest Landau levels.", "revisions": [ { "version": "v1", "updated": "2003-07-04T12:23:46.000Z", "comment": "5 pages including 2 figures" }, { "version": "v2", "updated": "2017-12-05T09:40:31.000Z" } ], "analyses": { "keywords": [ "fermi sea", "quantum teleportation", "particle-hole annihilation", "degenerate electron gas", "high magnetic field" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
