I started a bare minimum at *quantum probability* (redirecting *noncommutative probability space* etc.)

Some entries have long been secretly referencing such an entry, and I have cross-linked accordingly, for instance from *von Neumann algebra* and *quantum computing*.

I had the feeling somewhere we already had a detailed account of probability theory dually in terms of von NNeumann algebras, but if we do I didn’t find it(?)

]]>started an entry *interacting vacuum* with some pointers. For instance to

- Johann Rafelski,
*Vacuum structure – An Essay*, in pages 1-29 of H. Fried, Berndt Müller (eds.)*Vacuum Structure in Intense Fields*, Plenum Press 1990 (GBooks)

added some stuff to *Lamb shift*

also created a stub for *radiative correction*
