 Experimental tests of the Bell inequalities continue to be refined. Their analysis is delicate, employing sophisticated statistical models and simulations. (See Elkouss and Wehner 2016 and Graft 2016.) The significance of the tests remains a lively area for critical discussion. Meanwhile the techniques developed in the experiments, and related ideas for utilizing the entanglement associated with EPRB-type interactions, have become important in their own right. These techniques and ideas, stemming from EPRB and the Bell theorem, have applications now being advanced in the field of quantum information theory — which includes quantum cryptography, teleportation and computing (see  Quantum Entanglement and Information).
