I want to know if its possible to change (control)the spin up or down of 1 entangled particle so it would be possible to transmit data throughout the universe instantly.

Frame Dragger said:It is impossible to transmit Information FTL (Faster Than Light) using quantum Entanglment. It is poossible to change the spin, but for the recipient on the other end (call him Bob for formality) would only be able to see random noise. You need non-quantum (Classical) means of communication. You could meet before you part and agree on certain timings, etc... but then you've ALREADY communicated the information sub-c right? When you break down all of the other ideas you run into the same issue; "Spukhafte Fernwirking" certainly seems to exist, but in terms of using it to break the limits sets by Relativity and Causality are out. Sorry!
This doesn't mean Entangled partcles wouldn't be useful as means of communicating information, but you'd be doing it at or below 'c'. You should do some research into quantum computing, crptology, and sub-c secure communications. There ARE amazing properties of what you're talking about, they just happen to not break Causality.
lnsanity said:Why would the other only see random noise he cannot see the particle changing state ? can you clarify ? What do you mean by timing ? can you clarify that too ? a protocol is always decided in advance before transmitting a message...
Frame Dragger said:As I said, this is a subject that has been covered, probably dozens of times in this forum. JDo a search, and I guarantee you'll find all the answers you need.

The spin of an entangled particle can be controlled through various methods such as applying external magnetic fields or using lasers to manipulate the energy levels of the particle.
Controlling the spin of an entangled particle can have important implications in quantum computing and communication. It allows for the manipulation and transfer of information between entangled particles, which can be used for secure communication and faster computing.
Yes, it is possible to change the spin of only one entangled particle. This can be achieved by applying external fields or using specialized techniques such as quantum gates.
Yes, the spin of an entangled particle can be changed remotely through the use of quantum entanglement. This allows for the manipulation of the spin of one particle to affect the spin of its entangled partner, even if they are physically separated.
There are certain limitations to controlling the spin of an entangled particle, such as the uncertainty principle in quantum mechanics. This means that the exact spin state of an entangled particle cannot be determined with 100% accuracy, but rather it exists as a probability distribution.
