Quantum Entanglement Communication Radio

SUMMARY

The discussion centers on the concept of quantum entanglement communication, specifically the idea of using photons from distant stars for instantaneous communication. The original poster proposes a method involving a photon trap to hold entangled photons long enough for measurement and communication. However, established physics, particularly the quantum no-signalling theorem, confirms that entanglement cannot be used for faster-than-light communication, rendering the proposed method unfeasible. The consensus is that while the idea is intriguing, it contradicts fundamental principles of quantum mechanics.

Invention of the QE communication system through universe
Hello,

first from all, I am completely new and uneducated in physics. But from nothing I have had idea how to make this invention. And I have quite strong need to share it.
My mind found out how we can communicate with no delay through out our universe.
Seems quite fancy, isn't it? Yes, quantum entangled communication is working. But as far as I know it is useable only when you have nearby (up to few km range) source which can generate quantum entangled photon pair.

But now my idea - why we can't use photons generated from stars? There are plenty of photons! And we know these photons are coming from extremely far galaxies.
I guess the problem is, probability that we will find entangled photons at two spots where we want is...? Small.

But what if we will find just one entangled photon? What if we can use photon trap and work with this photon?
What if we can interfere the photon in whatever way to make measurable change.
What if we have entangled photons - one from transmitter, other from receiver. And they can last in the trap for time required for its measurement.

The only problem is to detect that the photons are entangled. If we have a trap for photons, we can work with them and listen for a pattern that we are sending.

If we would have a photon trap that will hold entanglement long enough, tell me one reason, why this could not work?

Procedure for communication would be:
1. Trap photons and measure their properties that we can affect.
2. Look for a pattern that we can both sending - affecting photons.
3. Once we will find such pattern, we found entangled photons.
4. Communicate through entangled photons as long as possible.

Because something tells me we have not invented such trap that can hold photon with its entanglement then the only possibility would be to:
Be able to intercept so many photons and measure all of them that chance for finding pair will be high enough.
Affect them if possible - as fast as possible.

I don't know why, but I am absolutely certain this could, one day, work, somehow in this way.
Now I would like to see your comments, why this can't work and why this is nonsense.

Thank you!

No, it is not possible to use entanglement to communicate as you’re thinking. We have many many threads here explaining why - a few of them appear in the “related threads” list below. You may also want to Google for “quantum no-signalling theorem”
