Does anyone know if the new in-line optical amplifiers (not switches!) have any effect on quantum crypto messages?
Optical
repeaters have to pass your signal through an intermediate electronic stage anyway, since we have no purely optical valve/transistor equivalents (bosons don't interact with each other at all).
This is not true. There is now a whole technology of optical amplifiers for fiber communications systems that used Ettrium doped fibers pumped
The proper name is "Erbium." But the rest of Dave Emery's commentary is accurate. Jim Bell jimbell@pacifier.com Klaatu Burada Nikto Something is going to happen.
