Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states

Haw, Jing Yan; Zhao, Jie; Dias, Josephine; Assad, Syed M; Bradshaw, Mark; Blandino, Rémi; Symul, Thomas; Ralph, Timothy C; Lam, Ping Koy


The no-cloning theorem states that an unknown quantum state cannot be cloned exactly and deterministically due to the linearity of quantum mechanics. Associated with this theorem is the quantitative no-cloning limit that sets an upper bound to the quality of the generated clones. However, this limit can be circumvented by abandoning determinism and using probabilistic methods. Here, we report an experimental demonstration of probabilistic cloning of arbitrary coherent states that clearly...[Show more]
