Noiseless Quantum Measurement and Squeezing of Microwave Fields Utilizing Mechanical Vibrations
Abstract
A process which strongly amplifies both quadrature amplitudes of an oscillatory signal necessarily adds
noise. Alternatively, if the information in one quadrature is lost in phase-sensitive amplification, it is
possible to completely reconstruct the other quadrature. Here we demonstrate such a nearly perfect phasesensitive
measurement using a cavity optomechanical scheme, characterized by an extremely small noise
less than 0.2 quanta. The device also strongly squeezes microwave radiation by 8 dB below vacuum.
A source of bright squeezed microwaves opens up applications in manipulations of quantum systems, and
noiseless amplification can be used even at modest cryogenic temperatures.
