As a result, measurements performed on one system seem to be instantaneously influencing other systems entangled with it.
But quantum entanglement does not enable the transmission of classical information faster than the speed of light.
Quantum entanglement has applications in the emerging technologies of quantum computing and quantum cryptography, and has been used to realize quantum teleportation experimentally.
At the same time, it prompts some of the more philosophically oriented discussions concerning quantum theory.
The correlations predicted by quantum mechanics, and observed in experiment, reject the principle of local realism, which is that information about the state of a system should only be mediated by interactions in its immediate surroundings.
Different views of what is actually occurring in the process of quantum entanglement can be related to different interpretations of quantum mechanics.
