Whats wrong with concept of "faster than light" information transfer device? (not about technical implementation, just about theory) [closed]
Yesterday, while lying in bed, an idea came to me, and I don’t understand why it won’t work?
Setup:
1.1) Two infinite stores of entangled pairs of photons, each connected to a double-slit device.
1.2)...

Transmitting Data faster than the speed of light using entangled particles [duplicate]
If we have a pair of super-asymmetrical entangled particles, and move them a light year away so that they retain their quantum entanglement, and we set a clockwise spin (or vertical polarization) as 0 ...

Can a non-local theory be consistent with special relativity?
If there was a non-local theory that explained quantum entanglement correlations, does it follow that it would violate special relativity?

Does the no signalling theorem in quantum mechanics beg the question?
I had always thought similarly and then came across a paper here that argues this.
The abstract is as follows:
Many authors state that quantum nonlocality could not involve any controllable ...

What are the implications of the EPR bridge information metric being invariant under all conditions, including distance in this universe?
What if the reason why instantaneous state information is able be transmitted between entangled particles through an EPR bridge is that the metric that this is conveyed in is invariant under all ...

How can resolution of particle entanglement be detected, and why can't it be faster than light communication?
Sorry for the length, but this is driving me crazy. And yes, there are other questions on this issue and I have reviewed them, but I cannot see the answer stated simply. What is different about my ...

Quantum entanglement and speed of transmitting information [closed]
Imagine Alice and Bob have two pairs of entangled particles, pair A, and pair B. Imagine they have agreed beforehand that pair A measurement preceding pair B measurement constitutes a bit with value 1 ...

Can entanglement witnesses on GHZ states with $n > 2$ violate the non-communication theorem?
In experiments involving entangled photons, measuring entanglement in systems with more than two particles ($n > 2$) often employs one photon as a herald to distinguish signal photons from noise. ...

Is it possible to know if an entangled particle's state is a superposition or collapsed? [duplicate]
I understand it's not possible to transmit information using entangled particles due to the randomness of the measure results.
But what if the act of measuring itself IS the information?
Let's say ...

FTL Communication using Quantum Entanglement (A new Approach) [closed]
Ok i have a proposition:
Imagine there are two people 1 on earth and other in space.
They syncronised their clocks before they left earth and agreed that they will factor in time dilation and ...

Communication via entanglement [duplicate]
For years now i have in my haed a thought experiment for information exchange via quantum entanglement. And i am aware that something must be wrong with it but i can't figure out what it is.
The ...

Instantaneous transmission of data across arbitrary distances via quantum entanglement [duplicate]
As a forward, I'm no a physicist or a student of it. In fact I'm pretty ordinary. So if I mischarecterize some concepts, bear with me.
So I was reading up on some of the new technologies and then I ...

Faster than light communication by entangled photons [duplicate]
Faster than light communication is not possible. If I measure the polarization of an entangled photon and it turns out to be right circularly polarized. In that instant, dont I know that someone ...

Please give me a single sentence explaining why faster-than-light morse code through entanglement isn't possible? [closed]
Problem with past explanations is they emphasize the need for random choice of measurement angle, but my understanding is that was only necessary in experiments seeking to remove any possible loop-...

Simultaneous measurements of two entangled particles [duplicate]
Experimental evidence reject the local hidden variable theory, so let's say quantum mechanics is right and the wave function does instantaneously collapse upon measurement.
Suppose we have two ...
