Minimally Destructive Fast Imaging of Single Atoms in an Optical Tweezer Array with Coherent Excitation
Rei Yokoyama, Takumi Kashimoto, Kosuke Shibata +8
Ultracold neutral atoms in an optical lattice and an optical tweezer array offer highly-controllable quantum many-body systems, utilized for various quantum science and technology…
Spin-Cat Qubit with Biased Noise in an Optical Tweezer Array
Toshi Kusano, Kosuke Shibata, Chih-Han Yeh +8
Bias-tailored quantum error correcting codes (QECCs) offer a higher error threshold than standard QECCs and have the potential to achieve lower logical errors with less space overh…
Precision spectroscopy in Yb+ ions
Jialiang Yu, Kai C. Grensemann, Chih-Han Yeh +5
We report on our progress on multi-ion spectroscopy with Yb+ ions. We first characterized the spatial homogeneity of the magnetic- and the rf-field. Subsequently, to equalize the i…
Probing new bosons and nuclear structure with ytterbium isotope shifts
Menno Door, Chih-Han Yeh, Matthias Heinz +24
In this Letter, we present mass-ratio measurements on highly charged Yb ions with a precision of and isotope-shift measurements on Yb on the …
Robust and scalable rf spectroscopy in first-order magnetic sensitive states at second-long coherence time
C. -H. Yeh, K. C. Grensemann, L. S. Dreissen +2
Trapped-ion quantum sensors have become highly sensitive tools for the search of physics beyond the Standard Model. Recently, stringent tests of local Lorentz-invariance (LLI) have…
Improved bounds on Lorentz violation from composite-pulse Ramsey spectroscopy in a trapped ion
Laura S. Dreissen, Chih-Han Yeh, Henning A. Fürst +2
In attempts to unify the four known fundamental forces in a single quantum-consistent theory, it is suggested that Lorentz symmetry may be broken at the Planck scale. Here we searc…
Coherent excitation of the highly forbidden electric octupole transition in Yb
Henning A. Fürst, Chih-Han Yeh, Dimitri Kalincev +7
We report on the first coherent excitation of the highly forbidden electric octupole (E3) transition in a single trapped Yb ion, an…
