Simultaneous Suppression of Thermal Phase Noise and Relative Intensity Noise in a Fiber Optic Gyroscope
Nobuyuki Takei, Martin Miranda, Yuki Miyazawa +1
The short-term sensitivity of a kilometer-long fiber-optic gyroscope is limited mainly by thermal phase noise and relative intensity noise. Increasing the phase modulation frequenc…
High-resolution spectroscopy and single-photon Rydberg excitation of reconfigurable ytterbium atom tweezer arrays utilizing a metastable state
Daichi Okuno, Yuma Nakamura, Toshi Kusano +4
We present an experimental system for Rydberg tweezer arrays with ytterbium (Yb) atoms featuring internal state manipulation between the ground S and the metastable ${}^3…
Two-photon comb with wavelength conversion and 20-km distribution for quantum communication
Kazuya Niizeki, Daisuke Yoshida, Ko Ito +6
Quantum computing and quantum communication, have been greatly developed in recent years and expected to contribute to quantum internet technologies, including cloud quantum comput…
Competition and interplay between topology and quasi-periodic disorder in Thouless pumping of ultracold atoms
Shuta Nakajima, Nobuyuki Takei, Keita Sakuma +3
Robustness against perturbations lies at the heart of topological phenomena. If, however, a perturbation such as disorder becomes dominant, it may cause a topological phase transit…
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…
Time-domain Ramsey interferometry with interacting Rydberg atoms
Christian Sommer, Guido Pupillo, Nobuyuki Takei +4
We theoretically investigate the dynamics of a gas of strongly interacting Rydberg atoms subject to a time-domain Ramsey interferometry protocol. The many-body dynamics is governed…
