Observation of two output light pulses from a partial wavelength converter preserving phase of an input light at a single-photon level
Rikizo Ikuta, Toshiki Kobayashi, Hiroshi Kato +9
We experimentally demonstrate that both a converted and an unconverted light pulses after wavelength conversion with various conversion efficiencies preserve phase information of a…
Non-classical two-photon interference between independent telecom light pulses converted by difference-frequency generation
Rikizo Ikuta, Toshiki Kobayashi, Hiroshi Kato +9
We experimentally demonstrated the Hong-Ou-Mandel (HOM) interference between two photons after visible-to-telecommunication wavelength conversion. In the experiment, we prepared a…
High-fidelity conversion of photonic quantum information to telecommunication wavelength with superconducting single-photon detectors
Rikizo Ikuta, Hiroshi Kato, Yoshiaki Kusaka +9
We experimentally demonstrate a high-fidelity visible-to-telecommunication wavelength conversion of a photon by using a solid-state-based difference frequency generation. In the ex…
Wide-band quantum interface for visible-to-telecommunication wavelength conversion
Rikizo Ikuta, Yoshiaki Kusaka, Tsuyoshi Kitano +4
We perform the first demonstration of a quantum interface for frequency down-conversion from visible to telecommunication bands by using a nonlinear crystal. This interface has a p…
