The vacuum, temperature and confinement requirements would seem to be huge problems relative to the exotic material requirement of current gates (Not to diminish the significance of accomplishing this in silicon). As far as I know these 'hard' problems have remained pretty constant in quantum computing. Are we making progress on any of them? Basically, in your opinion how are things progressing in the field with respect to the big problems with making quantum computing mainframe ubiquitous?
