A low-loss telecom-band nanofiber cavity for interfacing Yb atomic qubits
Seitaro Horikawa, Shinya Kato, Ryotaro Inoue +3
We demonstrate the fabrication of an optical nanofiber cavity designed for efficient interface with ytterbium (Yb) atoms at telecom-wavelength transitions. Replacing the convention…

Sub-Recoil Transverse Momentum Width in a Cold Ytterbium Atomic Beam
Toshiyuki Hosoya, Tomoya Sato, Ryotaro Inoue +1
We demonstrate the generation of a slow ytterbium atomic beam with a transverse momentum width of times the photon recoil associated with Bragg diffraction, and a flux of…

Taming Recoil Effect in Cavity-Assisted Quantum Interconnects
Seigo Kikura, Ryotaro Inoue, Hayata Yamasaki +2
Photon recoil is one of the fundamental limitations for high-fidelity control of trapped-atom qubits such as neutral atoms and trapped ions. In this work, we derive an analytical m…
