Wave holography is the concept that waves have the ability to store "information." Karl Pribram, a neurosurgeon and a professor of psychology and psychiatry at Standford University has become famous through his theory of the "holonomic brain," a theory which states that our thoughts and our memories are stored in waves. This theory began when Pribram discovered the startling similarity between optical holography and memory storage. Some troubling experiments earlier in the 20th century revealed that memory seemed to be stored in the brain, but in such a way that it was diffused throughout, and every part contained the whole. This is amazingly similar to an optical holograph; let me explain. An optical holograph is created by splitting a beam of light and shinning one part on an object, a china teacup say, and causing the other to interfere with the reflected light wave from that teacup. This "interference pattern" is then captured on a photographic plate, and when one shines a light through that photographic plate it creates a virtual image of a floating china teacup. Cool right? But it gets weirder; if you cut that plate into a tenth of its size and shine a light through it you will still get a full image of a china teacup, albeit a little blurry. Again, this is similar to how memory works in the brain; Karl Lashely did some experiments with rats in which he tried to eliminate a memory he had given them (jumping over a stick) by systematically destroying their brain. Even after he had destroyed nearly all of the brains of his laboratory rats (cruel I know) the rats still remembered to jump over the stick, though of course their motor coordination was severely impaired.
Please note that the above is a [i]severely[/i] simplified version of the holonomic brain theory. The full theory involves research on microtubles in neurons and their unique ability to generate coherent focused light, a concept called "super-radiance", etc. If you wish to discover more, please do your own research.
The important thing from this is that waves have the curious property of "storing information", in the form of 3d images. Well, taking this into account with my previous theory, a wave should be able to travel from mind 1 to mind 2 instantaneously, using non-local connections. This wave would have been encoded with all the information from the sender.
