Author(s): Evan Meyer-Scott, Marek Bula, Karol Bartkiewicz, Antonín Černoch, Jan Soubusta, Thomas Jennewein, and Karel Lemr We propose a linear-optical scheme for an efficient amplification of a photonic qubit based on interaction of the signal mode with a pair of entangled ancillae. In contrast to a previous proposal for qubit amplifier by Gisin et al. [ Phys Rev. Lett. 105 070501 (2010) ], the success probability of ou... [Phys. Rev. A 88, 012327] Published Fri Jul 26, 2013
