Visible 780 nm SBS laser with mW level threshold in an ultra-high 145 million Q integrated waveguide resonator

TL;DR: In this article , the authors demonstrate several quantum algorithms on a programmable gate-model neutral-atom quantum computer in an architecture based on individual addressing of single atoms with tightly focused optical beams scanned across a two-dimensional array of qubits.

TL;DR: In this paper , the authors measured a linear frequency gradient consistent with the gravitational redshift within a single millimeter scale sample of ultracold strontium and improved the fractional frequency measurement uncertainty by more than a factor of 10, reaching 7.6$\times 10^{-21}$.

TL;DR: In this article, a quantitative analysis of the Rydberg sensor's sensitivity to oscillating electric fields with frequencies between 1 kHz and 1 THz is presented, using a combination of analytical and semi-classical Floquet models.

TL;DR: In this paper, an optical clock was proposed to improve the stability and power efficiency of the optical frequency standard for satellite navigation. But it is not suitable for use outside of a well-controlled laboratory environment, since it is often bulky, power-hungry, and inefficient.
