I'm interested in getting an overview of the leading approaches to quantum computing from a physics perspective. I've read most of Nielsen and Chuang, but its chapter on physical realizations looks extremely out of date.
Is there a resource at a similar level that covers the approaches used by, e.g. Google, Microsoft, Pan's group, and IBM? I've seen a lot of qualitative material, but it's usually aimed at computer science people and thus physics-free. I'm looking for something at the level of "here's the Hamiltonian describing a single qubit, here's the interaction Hamiltonian describing a gate, here's how readout is done", and so on.
