BEC's and cryonics

  1. Aug 1, 2011 #1
    I have a question regarding Bose-Einstein condensates. Let's say, hypothetically speaking, that we were able to overcome all the technical issues involved in cryogenic freezing and were able to freeze and reanimate people with ease. If we cryogenically froze a human being, then converted the frozen being to a BEC, would we be able to later undo the conversion to a BEC and then reanimate the cryogenically frozen human?

    In other words, is the following chain of events possible?

    Living human -> Cryogenically frozen human -> Bose-Einstein condensate -> Cryogenically frozen human -> Living human

    Is that possible, or does becoming a BEC do something irreversible to the atoms that make up the cryogenically frozen human?

    Abstracting of human being a subject to the process, how do you want to make a condensate of mixture of different molecules?
    You may create BEC only of identical bosons.

    I thought that a BEC is simply the result of cooling something down to just a tiny fraction of a degree above 0K.

    No certainly not ... Bose-Einstein condensation is a phenomenon unique to systems of weakly-interacting, spin-zero bosons. The root concept is Bose-Einstein statistics, which say that an arbitrary number of identical bosons can occupy the same quantum state. This is distinct from the case of identical fermions, which obey Fermi-Dirac statistics, and CANNOT occupy the same quantum state according to the Pauli Exclusion Principle.

    So would this prevent quantum teleportation of a human being? I thought that, in order to quantum teleport a macroscopic object, you'd have to cool it down to almost absolute zero. So what would happen to a cryogenically frozen human body if we got it down to, say, 1 millikelvin? Actually, would that temperature be too high to maintain entanglement?

    You should never jump to something else before understanding the basics. Here, you clearly have not understood what a BEC is, but you're already speculating on top of that about quantum teleportation.

    Figure out and straighten out your faulty understanding of BEC, and why not everything cooled down to such low temperatures will exhibit such condensation. Don't be so eager to apply something you don't understand yet to do something else.
