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

Interactions and charge fractionalization in an electronic Hong-Ou-Mandel interferometer.
This work considers an electronic analog of the Hong-Ou-Mandel interferometer, where two single electrons travel along opposite chiral edge states and collide at a quantum point contact and shows that charge and neutral modes interfere with each other, leading to satellite dips or peaks in the current noise.
