popularmechanics.com — New experiments using Heisenberg's uncertainty principle extend the range of quantum cryptography, an advanced method of communicating in unbreakable code. Finding a way to keep snoops from tapping into other people's information is a challenge that has gone to the subatomic level. First proposed in 1984, quantum cryptography (QC) promises to send

That I know, but what I meant, was blocking the "changed" photons that were observed and repeating them in their "unchanged" in the same way the original signal was transmitted.Because if it measured them, it would know what they were pre-change.would that be not possible, becuase if that wasn't possible, how would it be possible to transmit properly in the first place?
