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…
Sub-SQL electronic field sensing by simultaneously using quantum entanglements and squeezings
X. N. Feng, M. Zhang, L. F. Wei
Quantum entanglement and quantum squeezing are two most typical approaches to beat the standard quantum limit (SQL) of the sensitive phase estimations in quantum metrology. Each of…
Experimental evidences of a current-biased Josephson junction device can be worked as a macroscopic "Boson" or "Fermion" and the combination
P. H. Ouyang, S. R. He, Y. Z. Wang +4
According to the statistical distribution laws, all the elementary particles in the real 3+1-dimensional world must and only be chosen as either bosons or fermions, without excepti…
