Eavesdropping Is Not Possible

A friend of mine sent me an email with this comment,

“Single photon physics provides secure communication. If I do coding with photons, eavesdropping is not possible. A person who tries to eavesdrop, destroys the photon in the process” Dr. Steve Harris, Stanford University, 2008.

Got me thinking. In a photonics world based on quantum theory this is a correct statement, I would be the last person on Earth to disagree with an esteemed professor such as Steve Harris.

However, given that the photon probability distribution is a modified Gamma distribution and not a Gaussian distribution I was able to construct a different model of the photon that agrees reasonably well with Oulton et al, 2008 results. Caution: this model does need futher testing. This new model suggest that it is not possible to have secure communications with single photon physics.

June 18 2009 Badlands Interview

The June 18 2009 Badlands Radio Show interview is now available at iSETI LLC. 

Or directly on the blog:

Part 1, Badlands Interview 06/18/2009 (Duration 01:30:23)

Part 2, Badlands Interview 06/18/2009 (Duration 01:21:02)

Note that the interview proper starts 33 mins & 25 secs into Part 1. It is easier to jump straight to the interview at the iSETI LLC site.

ISDC 2009 went very well

I’m was very pleased with ISDC 2009. It was well organized and there were a lot of very good talks by various presenters at the different tracks during the conference. The kids space station design contest (NSS-NASA-and I forget the 3rd organization)  inspired a lot of grade school teams from around the world!

My presentation, “Stealth, Invisibility and Deep Space Radiation Shielding” was very well attended. There were more than 40 in the audience, and many, many questions. I’ve posted the presentation and video at iSETI LLC’s white papers.
