Secure quantum communication: Safe from hackers

Keeping communication safe from prying eyes and ears. It's why the ancient Greeks had their whispers. It's what inspired the enigma machine of World War II, and today, digital encryption. But all of these could be compromised. The problem is when someone listens in on secret communication, or copies sensitive data, it can be impossible to tell.
But today's engineers working on communication systems of tomorrow have a plan to change that. They call it "secure quantum communication." Sorry, hackers.

Quantum internet live mfc might be a reality in our time. Amazing technology.

Will photon not disturb by wire or medium (random) which may still send that data is not secure

[jimbo]

yea i got a plan as well, the ending of escape from la

And, Quantum Communications will allow us to communicate with astronauts or robots on far away planets instantaneously. That means a pilot can drive a rover or helicopter on Mars and the device will not have to wait for strung out instructions because of the distance.

This doesn't actually work practically
