SCN: What does that mean?
DW: To make a comparison between a quantum computer memory and a classical computer memory let's suppose you had a memory of 300 classical bits that could roughly store a line of text. If you had a quantum computer composed of rather 300 quantum bits it could store more information than a classical computer composed of all the matter in the universe.
SCN: That would be pretty amazing, right?
DW: It would be pretty amazing. Yes.
SCN: What are the challenges in making this technology a reality?
DW: The caveat in what we do is that, although we're able to demonstrate the features of quantum teleportation, we don't do it very well yet. There's some imprecision in what we do, so one of the main challenges as far as using teleporting on a quantum computer is to be able to do it with much more precision much higher accuracy. So one of the main challenges we have is to improve the accuracy of the teleportation we do. The second main challenge is to be able to do it on a very large number of quantum bits to do an interesting quantum computing algorithm.
SCN: How about Star Trek type teleportation, will that ever be possible?
DW: Well not in my lifetime, I think that's a pretty safe bet. In principal, the basic ideas that are employed with what we do with quantum teleportation could be done to accomplish essentially what's the teleportation in Star Trek and the movie Jumper, but again the primary difference is that in quantum teleportation we're not transforming matter, so you need all the matter that would compose a person in one place and all the matter that would realize the person in the other location as well. So in principal it could be done but I wouldn't invest in any quantum teleportation companies.
