Resources to study superconducting quantum hardware for beginners

Question

I want to start studying quantum hardware, in particular I'm interested on superconducting qubit. Are there any valid resources for a beginner (notes, lecture...)? I'm an electronic engineer and I have some knowledge of quantum mechanics and quantum computation

Answer 1

One of the main resources in general, would be:

• Krantz, Philip, et al. "A quantum engineer's guide to superconducting qubits." Applied physics reviews 6.2 (2019) [arXiv:1904.06560]

I usually find the thesis to be very beginner-friendly, as they explain most things in much more detail than papers.
