is they can detect a hack on the data (apparently even if it's simply a
regurgitation of the original) because the 'noise' created by the
tampering itself appears to leave a 'standard recognizable signature'.

Sj: line implies this is way above my pay-grade.

I can't parse the technical stuff. Does the last paragraph mean
they broke "old quantum crypto"?
