@cabe, the translation of the spin of a single photon at the receiving end is nothing short of Star Trek tech.  The way eavesdroppers can be detected is also a plus.  The grid has needed more security for some time now.

Cabe, this is a very interesting development.  I do wonder about your characterization of the technique as involving physics, not math.  I really thought that all physics used mathematics.

Thanks for covering the important subject of grid management, especially the fact that utilities use it to mix and match various sources of renewable energy as needed. And the fact that without such security systems, data transmitted can be intercepted.

The fact that a single grid issue caused one of the largest outages on the east coast, and let the company Enron take advantage of the west coast is why we need better protection for the grid. Redundancies and communication protection is essential.

I heartily agree, Cabe. Plus, I live in California, where some of the worst overcharging occurred.

Ann,

Were you in California when Enron was manipulating the power distribution?

Yep, lived here all my life. A federal court ruled yesterday that we're supposed to get rebates from that mess--finally! After more than 10 years. http://www.latimes.com/business/money/la-fi-mo-court-says-rebates-due-california-20130404,0,5301337.story

The $52 dollars for all 48M residents of California is a small and insulting consolation. Buy hey, it's something.

I agree, it's late and insulting. But it's $52 better than $0, and all of it is a lot better than nothing. BTW, I think you meant 48MM; 48M is 48,000.

 Again, great post.

Great post Cabe--very informative.  OK, it's time to show my lack of understanding once again.  Would you mind indicating the following?

 1.) Can you tell me the level of redundentcy generally used (and needed) for the "grid"?  Are we looking at multiple redundancy or single?

 2.)  Is there a Federal "mandate" for redundancy or is that decision left up to the individual utility providers?

3.) Do you know if the "Fed" is making any effort at all to upgrade what must be a very well-worm system?

4.) Is this technology now being used or is it still in developmental stages?

Again, great post.
