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…
