An input-output approach for giant atom scatterings beyond the dipole approximation
S. R. He, S. N. Wang, Y. L. Zhang +2
A giant atom is an artificial matter configuration whose spatial scale is comparable to the wavelength of the interacting electromagnetic wave, such that the usual electric-dipole…

A broadband single microwave-photon detector insensitive to the thermal noise
Y. Q. Chai, M. Y. Wang, S. N. Wang +2
Thermal noise is one of the physical obstacles that constrain the achievable detection sensitivities of various detectors. Indeed, as we showed in a recent paper (PRB 111, 024501 (…

Measuring weak microwave signals via current-biased Josephson Junctions II: Arriving at single-photon detection sensitivity
Y. Q. Chai, M. Y. Wang, S. N. Wang +2
It is well known that the current-biased Josephson junction (CBJJ) can serve as a Josephson threshold detector (JTD) for the sensitive detection of weak microwave signals. Based on…
