Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography promises more effective protection. It makes communication secure against eavesdropping by relying on the laws of quantum physics. However, the path toward a quantum internet is still fraught with technical hurdles.

      We have proven that’s impossible. Speed limit c Einstein enforced.

        Teleportation is instantaneous; there is 0 travel time.🤦‍♂️

        Depends on how much time you got innit

        Why impossible? Genuinely curious

          To simplify - c is the maximum speed at which a “cause” can be transferred.

          If I send a radio signal to turn on a light, and the light will only turn on in response to that signal, the signal cannot travel faster than c otherwise it would not have been able to turn on the light.

          Physics. But their is scientific consensus that you can’t transfer information faster than light. Our maths for both quantum physics and Einsteinian physics have both proven its impossible. Ohh and it fundamentally breaks causation. Grandfather paradox type shit.
