The calculation rather disregards the immense potential of compression. After all, the basic blueprint of a human being is written in the DNA which is rather less than one Gigabyte, Of course, this doesn't encode for all the experiences and environmental and random factors that lead to a particular human being at a particular point in time. However, it would seem that a vast amount of compression could be achieved by encoding, for instance, cell types and recording the approximately 10 trillion locations would achieve huge compression. Recording the state and configuration of the brain would require, for instance, about 10,000 trillion items on information, but still vastly less than the three-dimensional high res photocopy approach.
Of course, this lossy compression "JPEGing" of a human means the result wouldn't be exactly the same as the original. However, it also shows that this isn't really teleporting a human being. It's faxing one to make a copy. Real teleportation would actually require some form of manipulation of space-time to "move" the original,
