Proposal for optical parity state re-encoder. (English) Zbl 1152.81722

Summary: We propose a re-encoder to generate a refreshed parity encoded state from an existing parity encoded state. This is the simplest case of the scheme by A. Gilchrist et al. [Phys. Rev. A 75, 052328 (2007)]. We give a detailed experimental arrangement for the re-encoder and show that it is possible to experimentally demonstrate with existing technology parity encoded quantum gates and teleportation.
