Long-distance single photon transmission from a trapped ion via quantum frequency conversion
Thomas Walker, Koichiro Miyanishi, Rikizo Ikuta +7
Trapped atomic ions are ideal single photon emitters with long lived internal states which can be entangled with emitted photons. Coupling the ion to an optical cavity enables effi…
Polarization insensitive frequency conversion for an atom-photon entanglement distribution via a telecom network
Rikizo Ikuta, Toshiki Kobayashi, Tetsuo Kawakami +8
Quantum network with a current telecom photonic infrastructure is deficient in quantum storages that keep arbitrary quantum state in sufficient time duration for a long-distance qu…
Mach-Zehnder interferometer using frequency-domain beamsplitter
Toshiki Kobayashi, Daisuke Yamazaki, Kenichiro Matsuki +7
We demonstrated the first-order interference between coherent light at 1580 nm and 795 nm by using frequency-domain Mach-Zehnder interferometer (MZI). The MZI is implemented by two…
