I find the editorialized title misleading. They trapped 17000 atom pairs in an optical lattice and demonstrated a high-fidelity quantum gate between the atoms of each pair in parallel. There is no interaction between the atoms of different pairs and no individual control. The experiment demonstrates a very robust gate scheme, but is a long way from a programmable computer.

With the hype QC these days, I find it hard to separate hype from real progress.

its still more than my nephew managed to achieve this morning

ETHZ news page is always overhyped. There is good research coming from there but their marketing is never worth reading.

I have questions. Is he attempting to build a quantum gate array? Seems kind of unfair to compare one person's efforts with a well-established university, if so. :P

What is overhyped about: "A new trick brings stability to quantum operations". Are people complaining about the HN title as if it's the article's title?

Reminds me the state of nuclear fusion.
