Coherent superpositions of photon additions and subtractions for noiseless amplification and advanced quantum state manipulation
Alessandro Zavatta, Massimiliano Locatelli, C. Polycarpou, Marco Bellini · International Conference on Quantum Information · 2011
We experimentally realize coherent superpositions of single-photon additions and subtractions to perform a rich variety of complex state manipulations. Some of our recent results in this direction, including noiseless amplification, will be described.
