The use of quantum entanglement in communication and computation

 the counterintuitive predictions of quantum mechanics were verified in tests where polarization or spin of entangled particles were measured at separate locations, statistically violating Bell's inequality.^[6][7][8][9] This established that the correlations produced from quantum entanglement cannot be explained in terms of local hidden variables, i.e., properties contained within the individual particles themselves. However, despite the fact that entanglement can produce statistical correlations between events in widely separated places, it cannot be used for faster-than-light communication.^{[10][11][12]: 453}

Quantum entanglement has been demonstrated experimentally with photons,^[13][14] electrons,^[15][16] top quarks,^[17] molecules^[18] and even small diamonds.^[19] The use of quantum entanglement in communication and computation is an active area of research and development.
