Generation of spectrally factorable photon pairs via multi-order quasi-phase-matched spontaneous parametric downconversion
Fumihiro Kaneda, Jo Oikawa, Masahiro Yabuno +5
For advanced quantum information technology, sources of photon pairs in quantum mechanically factorable states are of great importance for realizing high-fidelity photon-photon qua…
Quantum detector tomography of superconducting nanostrip photon-number-resolving detector
Mamoru Endo, Tatsuki Sonoyama, Mikihisa Matsuyama +6
Superconducting nanostrip photon detectors have been used as single photon detectors, which can discriminate only photons' presence or absence. It has recently been found that they…
Massive-mode polarization entangled biphoton frequency comb
Tomohiro Yamazaki, Rikizo Ikuta, Toshiki Kobayashi +5
A frequency-multiplexed entangled photon pair and a high-dimensional hyperentangled photon pair are useful to realize a high-capacity quantum communication. A biphoton frequency co…
