A dual-region ytterbium tweezer apparatus with an in-vacuum nanofiber cavity
Shunichiro Hashimoto, Hideki Ozawa, Yusuke Hisai +2
We present a dual-region experimental apparatus for trapping single atoms of the fermionic isotope ytterbium-171 () with optical tweezers in a science chamber…
Strong coupling of a reconfigurable Yb atom array to a tunable telecom-band nanofiber cavity
Hideki Ozawa, Neville Chen, Yusuke Hisai +13
Nanophotonic cavities provide strong atom-photon coupling in a compact, directly fiber-coupled geometry, while a reconfigurable array of Yb atoms combines high-fidelity gat…
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…
Scalable Networking of Neutral-Atom Qubits: Nanofiber-Based Approach for Multiprocessor Fault-Tolerant Quantum Computer
Shinichi Sunami, Shiro Tamiya, Ryotaro Inoue +2
Neutral atoms are among the leading platforms toward realizing fault-tolerant quantum computation (FTQC). However, scaling up a single neutral-atom device beyond atoms…
