Quantum Entanglement and Useful Information

  1. Sep 24, 2011 #1
    The title is quite explanatory of this post. It has been suggested in other posts that quantum entanglement may be used to send usable information at speeds which may be viable for interstellar distances, making viable the holograms of Star Wars.

    However, as I understand it, sending information from the atoms entangled on one end of an interstellar Internet system would break the entanglement with the atoms at the other end of the system, because you have to manipulate the atoms at your end, hereby making the system pretty useless, and hence upholding Einstein's universal speed limit.

    I'd just like some confirmation of this, I can't remember exactly what happens.

    That question is still being studied as far as I understand it thier is a manner that has been suggested to create superluminal communication using an aspect of double slit

    http://en.wikipedia.org/wiki/Quantum_eraser_experiment the double slit method mentioned in Wiki

    http://www.engadget.com/2011/08/21/quantum-entanglement-could-mean-completely-secure-data-transfer/ this is a fairly new article


    This process currently has promise not only can you get secure data transfer but the process of that data in a quantum computer has been estimated to be 15 to 20 times faster than computers today.

    particle entangled diodes are currently been shown to have measurable usages and are being developed and improved upon. This is a recent article from what I can tell that explains the process and recent technology developements in entangled diodes
