Scientists develop low-loss, all-fiber system for strong and efficient coupling between distant atoms

A team of scientists from Waseda University, the Japan Science and Technology Agency, and the University of Auckland developed an integrated, all-fiber coupled-cavities quantum electrodynamics (QED) system, in which a meter-long portion of conventional optical fiber seamlessly and coherently connects two nanofiber cavity-QED systems.

“This kind of system may enable quantum computation, free from the limited computational power that systems today experience, and quantum networks that transfer and process quantum information generated by quantum computers,” says Takao Aoki, professor of applied physics at Waseda University and leader of the research team. “In the future, such quantum information science technology may help provide breakthroughs that may change our society drastically, such as the discoveries of new materials and pharmaceutical drugs.”

The team’s study was published in Nature Communications on March 11, 2019.
