Room-temperature addressing of single rare-earth atoms in optical fiber
Mikio Takezawa, Ryota Suzuki, Junichi Takahashi +6
Rare-earth (RE) atoms in solid-state materials are attractive components for photonic quantum information systems because of their coherence properties even in high-temperature env…
Enhancing the stimulated emission of polarization-entangled photons using passive optical components
Ryo Nozaki, Yoshiro Sato, Yoshitaka Shimada +7
Bright sources of polarization-entangled photon pairs are essential components for quantum information technologies. In general, it is necessary to introduce a resonator that combi…
Continuous-time quantum walk spatial search on the Bollobás scale-free network
Tomo Osada, Bruno Coutinho, Yasser Omar +3
The scale-free property emerges in various real-world networks and is an essential property which characterizes the dynamics or features of such networks. In this work we investiga…
Quantum interferometric generation of polarization entangled photons
Haruka Terashima, Satoshi Kobayashi, Takaho Tsubakiyama +1
Quantum interference, like Hong-Ou-Mandel interference, has played an important role to test fundamental concepts in quantum physics. We experimentally show that the multiple quant…
