Logical entanglement distribution between distant 2D array qubits
Yuya Maeda, Yasunari Suzuki, Toshiki Kobayashi +3
Sharing logical entangled pairs between distant quantum nodes is a key process to achieve fault tolerant quantum computation and communication. However, there is a gap between curr…

Channel-selective frequency up-conversion for frequency-multiplexed quantum network
Shoichi Murakami, Shunsuke Hiraoka, Toshiki Kobayashi +2
We demonstrate channel-selective frequency up-conversion from telecom wavelengths around 1540 nm for optical fiber communication to visible wavelengths around 780 nm, based on seco…
