comment decoherence free subspace of a single photon
Basically what you are looking at is to find whether there are entangled states in this family that are fixed points of the decoherence operator (or at least nearly so). To know what will happen you therefore need to know what decoherence operator you expect to act here.

comment When do the von Neumann projections occur and what causes them?
I have taken a brief look at your paper and intend to read it more fully, it is interesting. How do you deal with the nonlocality problem? Say if you have a Bell state and one observer is doing the measurement, how do you ensure correlated outcomes and collapse and still maintain local unitary evolution?

comment What is the physical size of a black hole?
Is this really true though? I was wondering about this myself. If you look at the coordinates of the objects as the asymptotic observer sees it, the object approaching the event horizon actually slows down and does not cross the horizon. I am happy to rewrite my answer if you can convince me that it is only the light rays that make the object appear as if it had not crossed the horizon but that it actually did.

comment Can quantum annealing be used for factorization?
Can you provide some references for this? Sounds very intriguing.
