A photonic quantum engine driven by superradiance
Jinuk Kim, Seung-hoon Oh, Daeho Yang +3
Performance of nano- and micro-scale heat engines can be improved with a help from quantum mechanical phenomena. Recently, heat reservoirs with quantum coherence have been proposed…
Entropic comparison of Landau-Zener and Demkov interactions in the phase space of a quadrupole billiard
Kyu-Won Park, Juman Kim, Jisung Seo +3
We investigate two types of avoided crossings in a chaotic billiard within the framework of information theory. The Shannon entropy in the phase space for the Landau--Zener interac…
Locking Multi-laser Frequencies to a Precision Wavelength Meter: Application to Cold Atoms
Junwoo Kim, Keumhyun Kim, Dowon Lee +6
We herein report a simultaneous frequency stabilization of two 780-nm external cavity diode lasers using a precision wavelength meter (WLM). The laser lock performance is character…
Precise and extensive characterization of an optical resonator for cavity-based quantum networks
Dowon Lee, Myunghun Kim, Jungsoo Hong +6
Cavity-based quantum node is a competitive platform for distributed quantum networks. Here, we characterize a high-finesse Fabry-Perot optical resonator for coupling single or few…
Behavior of Shannon entropy around an exceptional point in an open microcavity
Kyu-Won Park, Jinuk Kim, Songky Moon +1
We have investigated the Shannon entropy around an exceptional point (EP) in an open elliptical microcavity as a non-Hermitian system. The Shannon entropy had an extreme value at t…
Observation of scalable sub-Poissonian-field lasing in a microlaser
Byoung-moo Ann, Younghoon Song, Junki Kim +2
Sub-Poisson field with much reduced fluctuations in a cavity can boost quantum precision measurements via cavity-enhanced light-matter interactions. Strong coupling between an atom…
