Virtual Noiseless Amplification

Janousek, Jiri; Chrzanowski, Helen; Hosseini, Sara; Assad, Syed; Symul, Thomas; Walk, N; Ralph, Timothy Cameron; Lam, Ping Koy


The unavoidable addition of noise during amplification is a well known signature of quantum mechanics. It is at the heart of fundamental results such as the no-cloning theorem, quantum limited metrology, quantum key distribution and the impossibility of increasing entanglement by local operations. Nonetheless one can still avoid the unavoidable by moving to a non-deterministic protocol. This novel concept and a linear optics implementation have been proposed [1] and experimentally realised for...[Show more]
