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? |

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. |

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

How can super massive black holes have a lower density than water? Would the water really be sucked into the black hole? Surely from the perspective of an outside observer, water would only approach the horizon but never actually cross it. So you would not need any replacement water. Is this wrong? I think floating might be possible if the black hole was surrounded by matter near the event horizon. |
