Offset-locking-based frequency stabilization of external cavity diode lasers for long-distance quantum communication
Takuto Miyashita, Takeshi Kondo, Kohei Ikeda +3
Quantum repeaters are required for long-distance quantum communication. For efficient coupling of quantum entangled photon sources with narrow-linewidth quantum memories we perform…
A compact frequency-stabilized pump laser for wavelength conversion in long-distance quantum communication
Kohei Ikeda, Yusuke Hisai, Kazumichi Yoshii +3
We demonstrate a compact frequency-stabilized laser at 1064 nm using Doppler-free saturation absorption spectroscopy of molecular iodine. The achieved laser frequency stability and…
Two-step frequency conversion for connecting distant quantum memories by transmission through an optical fiber
Shuhei Tamura, Kohei Ikeda, Kotaro Okamura +4
Long-distance quantum communication requires entanglement between distant quantum memories. For this purpose, photon transmission is necessary to connect the distant memories. Here…
Ultrabright narrow-band telecom two-photon source for long-distance quantum communication
Kazuya Niizeki, Kohei Ikeda, Mingyang Zheng +7
We demonstrate an ultrabright narrow-band two-photon source at the 1.5 -μm telecom wavelength for long-distance quantum communication. By utilizing a bow-tie cavity, we obtain a ca…
