Abstract: Abstract We investigate the correlation between surface roughness and corresponding T2 times of near-surface nitrogen-vacancy centers (~10 nm/5 keV implantation energy) in diamond. For this purpose we compare five different polishing techniques, including both purely mechanical as… read more here.

DOI: 10.1103/physrevlett.127.123202
Abstract: Qubit coherence times are critical to the performance of any robust quantum computing platform. For quantum information processing using arrays of polar molecules, a key performance parameter is the molecular rotational coherence time. We report… read more here.
