Loved the Book “How the Hippies Saved Physics” by David Kaiser

Posted on April 23, 2013 by David Prutchi Posted in Bell's Inequality Test, Chapter 8 - Entanglement, Physics Humor, QKD

How the Hippies Saved Physics www.diyPhysics.com David Prutchi PhDI just finished the book “How the Hippies Saved Physics” by David Kaiser and absolutely loved!

The book was fun and immensely educational regarding the seemingly unlikely seed of modern-day quantum information theory.  I must confess that when I first saw the book on the shelf at my local Barnes & Noble I dismissed it as yet another pseudo-scientific account of quantum physics.  However, I bought a copy after reading the following review in New Scientist:

“David Kaiser’s How the Hippies Saved Physics is a reminder of the unexpected influence a bunch of freewheeling 1970s physicists had on fundamental theories

IT’S certainly a provocative title, but for the life of me I could not recall an era to which How the Hippies Saved Physics might have applied. Things made more sense, though, on reading David Kaiser’s mention of two other books, both of which had left a big impression on me: Fritjof Capra’s The Tao of Physics and Gary Zukav’s The Dancing Wu Li Masters.

Air to Ground Quantum Key Distribution Achieved

Posted on April 10, 2013 by David Prutchi Posted in Chapter 8 - Entanglement, QKD
Quantum key distribution from airplane David Prutchi PhD www.diyPhysics.com

From Nauerth et al, “Air to Ground Quantum Key Distribution”

From Phys.org:

“A team of German physicists has successfully demonstrated an ability to perform quantum key distribution (QKD) exchange between an airplane in flight and a ground station, paving the way perhaps to the same kinds of communications between satellites and ground stations which could lead to a global quantum based secure communications network. The team presented their results at the QCrypt convention this past week.
