Engineering sub-Poisson light in a simple mirror and beam splitter system
Sun-Hyun Youn
Vacuum fluctuation, which is the intrinsic nature of an electric field can be measured via homodyne detection. Moreover, electric field intensity fluctuation are also related to va…
Hong-Ou-Mandel interference depends on the method of the erasing the beam path information
Sun-Hyun Youn
We study how the information of the beam path is related to the Hong-Ou-Mandel interference with two pulsed light sources. Through a simple model in which two photons in the form o…
Conditional Generation Scheme for Entangled Vacuum Evacuated Coherent States by Mixing Two Coherent Beams with a Squeezed Vacuum State
Sun-Hyun Youn
Conditions to generate high-purity entangled vacuum-evacuated coherent states ( were studied for two cascade-placed beam splitters, with one squeezed state i…
A balanced homodyne detector for high-rate Gaussian-modulated coherent-state quantum key distribution
Yue-Meng Chi, Bing Qi, Wen Zhu +5
We discuss excess noise contributions of a practical balanced homodyne detector in Gaussian-modulated coherent-state (GMCS) quantum key distribution (QKD). We point out the key gen…
Instant single-photon Fock state tomography
S. R. Huisman, Nitin Jain, S. A. Babichev +4
Heralded single photons are prepared at a rate of ~100 kHz via conditional measurements on polarization-nondegenerate biphotons produced in a periodically poled KTP crystal. The si…
Decoherence-induced wave packet splitting
Young-Tak Chough, Hyunchul Nha, Sang Wook Kim +2
We provide an intuitive interpretation of the optical Stern-Gerlach effect (OSGE) in the dressed-state point of view. We also analyze the effect of atomic damping in an experiment…
