is the vacuum the same as a quantum vacuum? Minor question but just wondering.
I think you seem to be using terms in ways that aren't quite in line with standard usage. Until you get some of the standard relationships between concepts a little more straight in your head, you will get answers to the questions that people think you might have asked, or that they think you ought to have asked. Keep at it! You probably need to do some more reading in parallel with asking questions on Physics Forums. When I get confused, I often try to read a different book on QFT, because it's often quite illuminating when you notice differences between presentations.i guess another question I would ask is what is the difference between the quantum field and the vacuum?
