Of all of Harry Harrison's works, Bill the Galactic Hero also has a 'actually moves the person' drive that's explained in enough detail to count, in the 'bloater drive' (!) Expand inter-atomic bonds way beyond what is actually feasable, pinning the back end of the ship in place, then pin the front end instead and reverse. Simple and dumb enough for a military farce c/w pulp SF parody.
(Of course, it's presented as ridiculous, and the problems are manifold, but that test, it passes.)
The Greg Bear stories in question, were 'Heads' (prelude) and 'Moving Mars' (explanation) which used the 'cosmic database' theory that was interesting at the time, and using absolute zero (yeah, I know) matter as a way of affecting and moving the actual matter by manipulating it in a means not dissimilar to entangling.('tweaking the location of the matter')
To it's credit, the challenge of the first novella is about reaching absolute zero, and the second about (amongst lots of other plot) the computational power necessary to isolate and move discrete matter - but it was about moving the matter wholemeal, not encoding to data.
And of course, Schlock Mercenary, and teraportation, involving lots and lots of miniature wormholes. (Plot point, but the in universe method that preceded it had the very failings we're discussing avoiding, used in gruesome and innovative ways)
