Tecnología cuántica, el nuevo campo de batalla entre Estados Unidos y China

[Thelonious J.]

en teoría una comunicación por entrelazamiento cuántico es "inhackeable" ya que no habría conexión entre los dos puntos de comunicación salvo las particulas entrelazadas.

Sorry, that's not possible. Entanglement can only be used to send random information, which is useless.

Let's say you and I share a few entangled particles, I observe my particles and cause the collapse of the wave function in a certain vector of values, your entangled particles have exactly the same values as mine. We shared random information which can be used as encryption keys for a symmetrical algorithm.

Entanglement is not used to send the messages, it's used to generate the random keys for the same symmetrical algorithms that we use everyday in the web.
