Actually, no, its not, really. The article I read on the subject was 
*purely* as a means to reduce the amount of switching needed, to reduce 
power usage and heat. It was an "alternate" design to existing ones, 
which would allow more speed, but at less cost. What, if anything, it 
had to do with quantum computing, from that article, would be rather 
unclear, since it quite literally never mentioned it at all.
