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…
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…
Realization of superabsorption by time reversal of superradiance
Daeho Yang, Seung-hoon Oh, Junseok Han +5
Emission and absorption of light lie at the heart of light-matter interaction. Although emission and absorption rates are regarded as intrinsic properties of atoms and molecules, v…
Coherent single-atom superradiance
Junki Kim, Daeho Yang, Seung-hoon Oh +1
Quantum effects, prevalent in the microscopic scale, generally elusive in macroscopic systems due to dissipation and decoherence. Quantum phenomena in large systems emerge only whe…
Generation of an optical Schrödinger-cat-like state in a non-ideal cavity by injecting opposite-phase atomic dipoles
Daeho Yang, Junki Kim, Moonjoo Lee +2
We propose a method to generate an optical Schrödinger-cat-like state in a cavity in a substantial decoherence regime. Even when the cavity decay rate is considerably large, a cat-…
Indirect measurement of three-photon correlation in nonclassical light sources
Byoung-Moo Ann, Younghoon Song, Junki Kim +2
We have observed the three-photon correlation in nonclassical light sources by using an indirect measurement scheme based on the dead time effect of photon-counting detectors. We f…
