Hi, In the US, quantum is all about neutral atoms right now, with ColdQuanta and QuEra releasing one machine after another and Amazon making them available. It is characterized by a large number of quantum bits.
Here are some recommended learning resources.
Bloqade
https://queracomputing.github.io/Bloqade.jl/dev/
This is a Julia-based tool provided by QuEra, and the algorithm and mechanism are introduced quite carefully.
Using Aquila

This one has a tutorial on the neutral atom machine that QuEra currently offers on amazon braket. There is a fee to run it, but you can use the real thing.
Pulser
https://pulser.readthedocs.io/en/stable/index.html
This is a library for neutral atoms provided by Pascal of France. It has quite a lot of tutorials.
Pulser

This is an introductory paper of Pulser.
