Low-loss polarization-maintaining router for single and entangled photons at a telecom wavelength
Pengfei Wang, Soyoung Baek, Masahiro Yabuno +3
Photon polarization serves as an essential quantum information carrier in quantum information and measurement applications. Routing of arbitrarily polarized single photons and pola…
Optimized Spectral Purity of Heralded Single Photons at the Telecom O-Band
Wu-Hao Cai, Soyoung Baek, Rui-Bo Jin +1
We report on optimizing the spectral purity of heralded single photons in the telecom O-band, where single photons can be propagated with low loss and low dispersion in a standard…
Spectral characterization of photon-pair sources via classical sum-frequency generation
Fumihiro Kaneda, Jo Oikawa, Masahiro Yabuno +5
Tailoring spectral properties of photon pairs is of great importance for optical quantum information and measurement applications. High-resolution spectral measurement is a key tec…
Direct generation of frequency-bin entangled photons via two-period quasi-phase-matched parametric downconversion
Fumihiro Kaneda, Hirofumi Suzuki, Ryosuke Shimizu +1
We report a simple scheme for direct generation of frequency-bin entangled photon pairs via spontaneous parametric downconversion. Our fabricated nonlinear optical crystal with two…
High-efficiency single-photon generation via large-scale active time multiplexing
Fumihiro Kaneda, Paul G. Kwiat
On-demand generation of indistinguishable single- and multi-photon states is a key technology for scaling up optical quantum information and communication applications. Nonlinear p…
Heralded single-photon source utilizing highly nondegenerate, spectrally factorable spontaneous parametric downconversion
Fumihiro Kaneda, Karina Garay-Palmett, Alfred B. U'Ren +1
We report on the generation of an indistinguishable heralded single-photon state, using highly nondegenerate spontaneous parametric downconversion (SPDC). Spectrally factorable pho…
