The 'generally accepted' theory on how to accomplish this well is some implementation of quantum entanglement.
A wormhole is another possibility, but connecting both ends of an Einstein-Rosen bridge to the same universe would render it too unstable to be used for any sort of communication, as it would collapse before light or radio signals could make it through. One could theoretically get around this by creating two wormholes to a separate universe, with the endpoints here separated by distance and the endpoints in the other universe very close (so that signals/matter/etc. travels to the other universe and back). In effect, this would work similarly to 'hyperspace' in some sci-fi (e.g. Babylon 5's jump gates).
