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…

Demonstration of local expansion toward large-scale entangled webs
Toshiyuki Tashima, Tsuyoshi Kitano, Sahin Kaya Ozdemir +3
We demonstrate an optical gate that increases the size of polarization-based W states by accessing only one of the qubits. Using this gate, we have generated three-photon and four-…
