Let's build a quantum radio receiver

[MisterIX]

Homework Statement:: I would like to write a science fiction story on how alien quantum communication could work and how scientist on Earth build the first "radio" receiver, entangling Quantums over big distances randomly.
Relevant Equations:: https://www.chemie.de/news/156198/schnellere-verschraenkung-entfernter-quantenpunkte.html

First question: if I can entangle two quantum dots over 5m by randomly firing laser impulses on them, how does the probability of entanglement for the same setup differ about distance?

Take a look at the no-communication theorem first. If that is not fatal to your approach you may want to continue the discussion in the science fiction section.

As I understand it, quantum entanglement let's two distant observers agree on an endless list of random numbers, that no one else can see or intercept. But neither side can influence what those numbers actually are. So those numbers are great for encoding and decoding information, but you still need some conventional method of transmitting the encoded data.

I'd recommend not using the word "quantum" to explain your technology. Just call it "zeta link" or some gibberish name. That way when public understanding of the physics changes you don't get stuck trying to explain what "dilithium" is and why it would have some relevance to anti-matter.

@Nugatori Is there really a science fiction section? Pls. post link!

Admitted, but if you were an alien, how would you build a Quantum radio sender, in broadcast, so that every civilisation Quantum admitted, could build a receiver. Which numbers would you rely on. For the zeta link.

Is there really a science fiction section?

LOL. Look up! I moved your thread to this section on July 11th.

You really should have put that in a spoiler tag box. Now all the young kids will be trying that!
