The achievement in question is the preparation of the neutral atoms, which realize qubits, on this grid. Controlling the placement of such a large number of individual atoms with just light is a somewhat recent breakthrough that is now maturing.

Addressing the atoms and letting them interact is an entirely different beast, but the prerequisite of placement is just as important.

I use the keyboard layout EurKey, which is available on KDE Plasma. It’s QWERTY but with European special characters on layer 5, i.e. they are accessed by Alt Gr.
