@article{Ferraro2018EnhancingPS, title={Enhancing photon squeezing one Leviton at a time}, author={Dario Ferraro and Flavio Ronetti and J{\'e}r{\^o}me Rech and Thibaut Jonckheere and Maura Sassetti and Thierry Martin}, journal={Physical Review B}, year={2018}, volume={97}, pages={155135} }

A mesoscopic device in the simple tunnel junction or quantum point contact geometry emits microwaves with remarkable quantum properties, when subjected to a sinusoidal drive in the GHz range. In particular, single and two-photon squeezing as well as entanglement in the frequency domain have been reported. By revising the photo-assisted noise analysis developed in the framework of electron quantum optics, we present a detailed comparison between the cosine drive case and other experimentally… Expand
