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.…

Here’s Why the Quantum World Is Just So Strange

It underlies our universe but it follows its own “rules,” which don’t make sense to the rest of us

In this week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why Quantum mechanics pioneer Niels Bohr said, “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.” Let’s look at some of the reasons he said that: https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The Show Notes and transcript follow. Enrique Blair: It’s really quite different from our daily experience. Quantum mechanics really is a description of the world at the microscopic scale. And it’s really weird, because there are things that initially we thought maybe were particles but then we learned that they have wave-like behaviors. And there are other things that we thought were waves and then we…

What is quantum mechanics? Well, weird. Very weird. The great quantum mechanics pioneer Niels Bohr said: “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.” How did the study of quantum mechanics come to be? Robert J. Marks discusses quantum mechanics with Dr. Enrique Blair. Show Notes 00:41 | Introducing Dr. Enrique Blair, a professor of electrical…
