What do you understand about quantum entanglement?

  1. Aug 14, 2015 #1
    i have a doubt, can quantum entanglement be our future source of sending signals to space without waiting a lot of light years to reach? please someone explain how quantum entanglement works in space and particles.

    It's common to think that quantum entanglement could support some sort of faster than light communications - but it can't. Entanglement cannot be recognized until the measurement results form both of the entangled particles are compared - and even then, many such comparisons need to be made to create a statistically significant verification that some spooky had been happening.

    thanks, and does the quantum field have different feeling or sense about space/time? another dimension? which dimension would quantum particles be?

    Quantum Field Theory uses the conventional 4 dimensional space-time of relativity.

    String theory however does postulate extra dimensions - but it is much more speculative - QFT has been confirmed experimentally to great precision.
