There are two types of quantum computers: atomic and electronic. Originally, we have heard of them to some extent as a company, but recently, due to the popularity of the trapped ion method, we are hearing more and more about them as a company.
The specific companies are
ColdQuanta
Pasqal
Atom Computing

Some of these will be expected to first appear on the Google Cloud Platform.
In contrast to superconductivity and silicon, which deal with electrons, ion traps and cold atoms, which deal with atoms, are in vogue.
I'm looking forward to the confrontation between electron-based quantum computers and atom-based quantum computers.
