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?
