Quantum entanglement — 305 discussions

I'm trying to understand why entanglement is said to be "spooky." The model I have is that 2 entangled particles are related, such that they have identical states when measured. The entanglement process is what ensures they have identical states. So it's no surprise they measure out the same...

Can quantum entanglement effect be explained by a carrier particle traveling along spacetime geodesics with a zero time component? Or perhaps traveling along normal geodesics and then falling back in time along a time-like curve? Either of these essentially forms inifinite-speed motion of the...

Quantum entanglement, if I understand it correctly, specifies the phenomenon where the scattered pieces of a particle somehow know the whereabouts of its other pieces. Does that mean that by taking a neutron from atom A and placing it away from atom A, the atom would know where the missing...

First post. There's something I don't quite understand about quantum entanglement and I'm hoping someone here can put me right. When I first heard about the Aspect experiment, I thought that it had to open the way forward for faster-than-light information transfer as follows: Bob is on...

I have a question. Is there anybody helping me explain this inequality or if you can prove it . Thanks
