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…

Efficient decoherence-free entanglement distribution over lossy quantum channels
Rikizo Ikuta, Yohei Ono, Toshiyuki Tashima +3
We propose and demonstrate a scheme for boosting up the efficiency of entanglement distribution based on a decoherence-free subspace (DFS) over lossy quantum channels. By using bac…
