Complementarity of which-path information in induced and stimulated coherences via four-wave mixing process from warm Rb atomic ensemble
Danbi Kim, Jiho Park, Changhoon Baek +2
We report a systematic approach for establishing a complementary relationship between the interference visibility, concurrence, and predictability in the crossing of induced and st…
Collective biphoton temporal waveform of photon-pair generated from Doppler-broadened atomic ensemble
Heewoo Kim, Hansol Jeong, Han Seb Moon
Photonic quantum states generated from atomic ensembles will play important roles in future quantum networks and long-distance quantum communication because their advantages, such…
Violation of Bell inequality by four photon Greenberger Horne Zeilinger state with a phase from a warm atomic ensemble
Jiho Park, Junghee Ryu, Heonoh Kim +1
A Greenberger Horne Zeilinger (GHZ) entangled state with a phase is crucial for realizing desired multipartite quantum states for practical applications. Here, we report violations…
Highly bright photon-pair generation in Doppler-broadened ladder-type atomic system
Yoon-Seok Lee, Sang Min Lee, Heonoh Kim +1
We report a bright photon-pair source with a coincidence counting rate per input power (cps/mW) of tens of thousands, obtained via spontaneous four-wave mixing from a Doppler-broad…
Experimental demonstration of error-insensitive approximate universal-NOT gates
Sang Min Lee, Jeongho Bang, Heonoh Kim +3
We propose and experimentally demonstrate an approximate universal-NOT (U-NOT) operation that is robust against operational errors. In our proposal, the U-NOT operation is composed…
