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 (…

Switchable coherent state stored quantum batteries with large ergotropies
Y. F. Li, S. R. He, P. H. Ouyang +2
Quantum battery (QB) is a conceptually new energy storage and conversion device, which consists usually of a quantum charger and an energy store (called usually as the QB for simpl…

Experimental demonstrations of Josephson threshold detectors for broadband microwave photons detection
Jia-Xing He, Ya-Qiang Chai, Peng-Hui Ouyang +2
Current-biased Josephson junctions (CBJJs) have been demonstrated as sensitive Josephson threshold detectors (JTDs) in the infrared range. In this letter, we show this kind of dete…
