Braunstein, S.L., Cerf, N.J., Iblisdir, S., van Loock, P. and Massar, S. (2001) Optimal cloning of coherent states with a linear amplifier and beam splitters. Physical Review Letters, 86 (21). pp. 4938-4941. ISSN 0031-9007Full text not available from this repository.
A transformation achieving the optimal symmetric N→M cloning of coherent states is presented. Its implementation requires only a phase-insensitive linear amplifier and a network of beam splitters. An experimental demonstration of this continuous-variable cloner should therefore be in the scope of current technology. The link between optimal quantum cloning and optimal amplification of quantum states is also pointed out.
