Arrest causes EEG flatline after 20-30 seconds. People have
been resuscitated from almost an hour of deep hypothermia,
animals after several hours. Devitrified brain slices indicate
near-normal EEG.

Any gas box connected to a cold reservoir and frozen and then reconnected
to a hot reservoir will regenerate normal energy distribution. Biological
systems are more complicated, but since they can be restarted from
vitrified stage it empirically falsifies the propositon.

I'd wish that's all what they'd lose. Current cryopreservation
includes people on (former) water ice for a week. Or worse.

What is 'subatomic and quantum data'?
