Emission of non-classical radiation by inelastic Cooper pair tunneling (1703.05009v1)
Published 15 Mar 2017 in cond-mat.mes-hall, cond-mat.supr-con, and quant-ph
Abstract: We show that a properly dc-biased Josephson junction in series with two microwave resonators of different frequencies emits photon pairs in the resonators. By measuring auto- and inter-correlations of the power leaking out of the resonators, we demonstrate two-mode amplitude squeezing below the classical limit. This non-classical microwave light emission is found to be in quantitative agreement with our theoretical predictions, up to an emission rate of 2 billion photon pairs per second.
