Quantum Computation – Video Encryption

One of the claimed opportunities for quantum information processing is highly secure private key encryption – here demonstrated in real time encryption and decryption of each frame of streamed video.

I see from the linked stories, the other more interesting aspect, non-local entanglement over real world distances also demonstrated (1mm and 600m mentioned). The encryption aspect is really just a result of the power, the processing density, of Qubits, but the non-locality raises all sorts of causality bypasses in real world physics, and communication channels behind the electromagnetic “ether”. Hence my interest in basic questions of what is information anyway !!!

(And Stevie Elliott puts Sunderland ahead of the Hammers … Yeehah, …. 1:2 with 2 minutes to go. Hammers biggest crowd of the season, 33,400 leaving in droves, 90 minutes up, 4 minutes added.)
