High-fidelity entanglement swapping and generation of three-qubit GHZ state using asynchronous telecom photon pair sources
Yoshiaki Tsujimoto, Motoki Tanaka, Nobuo Iwasaki +7
We experimentally demonstrate a high-fidelity entanglement swapping and a generation of the Greenberger-Horne-Zeilinger~(GHZ) state using polarization-entangled photon pairs at tel…
Visible light emission from a silica microbottle resonator by second and third harmonic generation
Motoki Asano, Shoichi Komori, Rikizo Ikuta +3
We report the first observation of nonlinear harmonic generation and sum frequency generation (SFG) coupled with stimulated Raman scattering (SRS) via the second-order (χ^{(2)}) an…
A high visibility Hong-Ou-Mandel interference via a time-resolved coincidence measurement
Yoshiaki Tsujimoto, Yukihiro Sugiura, Motoki Tanaka +9
We report on the observation of a high visibility Hong-Ou-Mandel interference of two heralded photons emitted from a spontaneous parametric down conversion~(SPDC) pumped by continu…
Observation of optomechanical coupling in a microbottle resonator
Motoki Asano, Yuki Takeuchi, Weijian Chen +5
In this work, we report optomechanical coupling, resolved sidebands and phonon lasing in a solid-core microbottle resonator fabricated on a single mode optical fiber. Mechanical mo…
Experimental demonstration of robust entanglement distribution over reciprocal noisy channels assisted by a counter-propagating classical reference light
Rikizo Ikuta, Shota Nozaki, Takashi Yamamoto +2
We experimentally demonstrate a proposal [Phys. Rev. A 87, 052325 (2013)] of a scheme for robust distribution of polarization entangled photon pairs over collective noisy channels…
Heralded single excitation of atomic ensemble via solid-state-based telecom photon detection
Rikizo Ikuta, Toshiki Kobayashi, Kenichiro Matsuki +7
Telecom photonic quantum networks with matter quantum systems enable a rich variety of applications, such as a long distance quantum cryptography and one-way quantum computing. Pre…
