Sadly, I don't know enough about it to have an opinion. I can quote the magic words "quantum entanglement" like anybody else, and like anybody else, my understanding pretty much stops at that point. I have the sense that it has the potential for what we might otherwise regard as simultaneous solutions of a system of equations. It puts me in mind of a previous fascination with holographic computation, where information can be represented in the form of a hologram and processed through another hologram to provide the solution. It would be inherently instantaneous. Now that I bring it up, I wonder what became of that line of development. In some cases, the utility of the technique is limited by the ability of the human operators to set up the problem statement.
