Abstract

We demonstrate an averaging process, corresponding to the harmonic-mean, that average quantum noise sources better than the basic arithmetic-mean strategy. Using simple linear optics, homodyne detection and feedforward, and it is tested on squeezed states. © 2010 Optical Society of America.
