I'm interested in knowing the structure of a CNOT gate, in quantum computing. THe problem with that is, that I've read how the structure of a nuclear quantum computer works, but I still don't understand how that can be implemented to create a quantum CNOT gate. I've read the article of the original proposal of Cirac-Zoller, but it wasn't explained very good, I guess, so I want to ask, if someone has a link to some publication where it's explained better than there, possibly with more pictures rather then formulas. Thanks.
Quantum Computing Devices: Principles, Designs, and Analysis, (2007) provides the background theory, followed by a chapter for each of the technologies that was actively being explored when it was prepared.
The experimental chapters provide detailed information that ties the experimental apparatus to its mathematical representation. I recommend this a a good starting point.
