Phase-continuous comparison of three all-optical time scales over 20 days
Dahyeon Lee, Kyungtae Kim, Zoey Z. Hu +11
Optical frequency standards have progressed rapidly over the past two decades, leading to the anticipated redefinition of the SI second by an optical frequency. However, time scale…
Optimized experiment design and analysis for fully randomized benchmarking
Alex Kwiatkowski, Laurent J. Stephenson, Hannah M. Knaack +6
Randomized benchmarking (RB) is a widely used strategy to assess the quality of available quantum gates in a computational context. RB involves applying known random sequences of g…
Experimental speedup of quantum dynamics through squeezing
S. C. Burd, H. M. Knaack, R. Srinivas +9
We show experimentally that a broad class of interactions involving quantum harmonic oscillators can be made stronger (amplified) using a unitary squeezing protocol. While our demo…
Rotational spectroscopy of a single molecular ion at sub part-per-trillion resolution
Alejandra L. Collopy, Julian Schmidt, Dietrich Leibfried +2
We use quantum-logic spectroscopy (QLS) and interrogate rotational transitions of a single CaH+ ion with a highly coherent frequency comb, achieving a fractional statistical uncert…
Precision frequency-comb terahertz spectroscopy on pure quantum states of a single molecular ion
Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz +7
Spectroscopy is a powerful tool for studying molecules and is commonly performed on large thermal molecular ensembles that are perturbed by motional shifts and interactions with th…
3-D Magneto-Optical Trap of Yttrium Monoxide
Alejandra L. Collopy, Shiqian Ding, Yewei Wu +5
We report three-dimensional trapping of an oxide molecule (YO), using a radio-frequency magneto-optical trap (MOT). The total number of molecules loaded is 1.5 ,…
