Metasurfaces for neutral-atom trapping
Chengyu Fang, Minjeong Kim, Mark Saffman +2
Trapped neutral atoms are one of the leading platforms for quantum information technologies, in particular for quantum computing, but scaling them to array sizes needed for utility…

Silicon-on-sapphire metasurfaces generate arrays of dark and bright traps for neutral atoms
Chengyu Fang, Minjeong Kim, Hongyan Mei +10
We demonstrated crystalline silicon-on-sapphire (c-SOS) metasurfaces that convert a Gaussian beam into arrays of complex optical traps, including arrays of optical bottle beams tha…
