How Spooky “Quantum Collapse” Can Give Us More Secure Encryption

If entangled photons linked to random numbers are transmitted, parties on either end can know, via high error rates, that they’ve been intercepted.

In a recent podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange but important to our future. They discussed “quantum communication” (generally, quantum encryption) and why safer quantum encryption might be easier to achieve than general quantum computing. https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The discussion of quantum communication begins at approximately 55:32. The Show Notes and transcript follow. Robert J. Marks: I know there’s lots of interesting quantum communication today. The NSF and the Department of Defense are throwing big bucks at it. What is it, just roughly? Enrique Blair: Quantum communication really is the use of quantum mechanics to share information in a secure manner.…
