Could we possibly use the property of particles that when split you can do that thing where they both are the same across vast distances? Could that possibly be used to create "Quantum Modem Chips"? Or something?

wat?


It doesnt help because even though they are the same you will only know that when you check it, and after that they stop being in sync.

So you cant really use it for anything.

Actually its pretty much the same thing as if you knew their states when they have just been split and then take em far from each other and look at the states.

Are you sure?
Cause I feel like we should be able to access the states of them on a known interval, and use the states to construct binary data.

I don't know the specifics, but the modern interpretation of quantum entanglement makes it useless for transmission of information. (The idea is that you still need normal communication of information in the first place in order to decode the information that was sent via the entanglement, having data sent through an entangled system alone would not be of any use) It's more of a curiosity than an actual useful property.

Personaly, I don't think FTL is as possible WITHIN a gravitational body as it would be in a (nearly) gravityless area of outer space. With in a gracitational body, there would be too many forces holding the object back, including atmospheric friction and the gravity itself. In outer space, there is no atmospheric fiction and very little gravity. Until we can send an object FTL I doubt we will be able to send data FTL.

And when did this become a RL science forum? Lol.

But think of this:
We can control cycles to the milisecond, so we just have to check the state of the particle on an interval, then we look for a specific pattern of let's just say one Kb, that when that has been found, we send another Kb to the person we're talking too, think of it as the tcp handshake. Only, it'd be the QEC handshake. Where each QEC chip has a specific 1024 qubit long identifier. Or something like that.

Transmission of data would destroy the entanglement.
Although there is work in weak-observation, so that it wouldn't be *entirely* destroyed, and would be more able to read its properties.

The trouble is, how do you "just measure" the things? They're subatomic particles, you can't measure them without also changing their states. It turns out that if you do the math you won't be able to get any information though by doing this. Even with the more sophisticated and less naive approach of using breaking entanglement itself as the means of communicating information, it still turns out that with enough mathematical rigor you can prove no information is transferable.

Oh.. Poopy...
Well that's stupid, what's the good of something if it can't help me get FTL internet speeds.

Did you happen to get this idea from Mass Effect...?

No, ever since I heard about quantum entanglement on the history channel, I've had this fleeting thought.

1.Create matrix
2.Put world population in matrix
3.Make new particle that can be used for this
