Abstract

It is wonderful that Henry is still creative and active at the age of 90. I first communicated with Henry in 1963 when I was with Fred W. Cummings at Ford Philco Aeronutronics in Newport Beach, CA (I left Cornell where I was working with Leonard Susskind and Johnny Glogower on the problem of time and phase operators in quantum mechanics. I returned to Cornell about 6 months later.). That is also when I first met Richard Feynman at Cal Tech and also when I first communicated by snail mail with Brian Josephson if I recall correctly. David Kaiser recalls my interaction with Henry about quantum entanglement in his book “How the Hippies Saved Physics.” Kaiser also wrote how Nick Herbert and I were key catalysts in the creation of the “billion-dollar” quantum information/cryptography/computer industry. Henry played a key role in Nick’s and my quixotic quest to use orthodox quantum mechanical entanglement as a direct stand-alone keyless locally decodable command-control-communication-channel C4 (On Apr 22, 2018, at 4:52 PM, Robert Addinall wrote: “Actually command-control-communications channel should be C3. For C4, it should be command-control-communications-computing. Although it starts with the letter C, the word “channel” is not usually included in the acronym (C2 for command and control, and C4ISR for command-control-communications-computing-intelligence-surveillance-reconnaissance). It’s nice that you are writing some of this up in honor of Henry’s birthday.”). This “failure” led to the modern-day no-go theorems that form the basis of practical quantum cryptographic networks like the Chinese satellite web.
