From http://www.livescience.com/28550-how-quantum-entanglement-works-infographic.html
Entanglement occurs when a pair of particles, such as photons, interact physically. A laser beam fired through a certain type of crystal can cause individual photons to be split into pairs of entangled photons.
The photons can be separated by a large distance, hundreds of miles or even more.
When observed, Photon A takes on an up-spin state. Entangled Photon B, though now far away, takes up a state relative to that of Photon A (in this case, a down-spin state). The transfer of state between Photon A and Photon B takes place at a speed of at least 10,000 times the speed of light, possibly even instantaneously, regardless of distance.
Well, it does not. There is no transfer of state, since the only state that has some information is the composite state, that says that, at any time, any observation will result in observing the particles in opposite states.
As my classical example illustrates. Did the observation of Alice influenced the state of Bob's ball instantaneously? [yes/no]

P.S. Are you confident with the concept of density matrixes in QM?
