Noncollinear parametric fluorescence by chirped quasi-phase matching for monocycle temporal entanglement
Akira Tanaka, Ryo Okamoto, Hwan Hong Lim +9
Quantum entanglement of two photons created by spontaneous parametric downconversion (SPDC) can be used to probe quantum optical phenomena during a single cycle of light. Harris [P…
Experimental Demonstration of Adaptive Quantum State Estimation
Ryo Okamoto, Minako Iefuji, Satoshi Oyama +4
The first experimental demonstration of an adaptive quantum state estimation (AQSE) is reported. The strong consistency and asymptotic efficiency of AQSE have been mathematically p…
Generation of broadband spontaneous parametric fluorescence using multiple bulk nonlinear crystals
Masayuki Okano, Ryo Okamoto, Akira Tanaka +2
We propose a novel method for generating broadband spontaneous parametric fluorescence by using a set of bulk nonlinear crystals (NLCs). We also demonstrate this scheme experimenta…
