I did graduate research in an area of experimental physics that was quite close to state of the art quantum computing research. It was very exciting, but all the research was pretty much in extreme conditions that aren't really usable for a realistic computing device (ultra-high vacuum, nanokelvin temperatures, high magnetic fields or laser trap confinement, etc.). From the looks of it this paper is in the same vein. Good progress, but the gate isn't quite "open" yet.
- uncoder0 9y agoThe 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?
- badspeler 9y agoThat's true but once Science conquers something, engineering isn't very far behind. The apparatus to build Bose-Einstein Condensates was a fucking monster of vacuums and quantum optics but now we can fit a Bose-Einstein Condensate on a microchip. https://arxiv.org/abs/0912.0553 https://arxiv.org/abs/0912.0553
- techdragon 9y agoI Just read that paper and while It’s hardly just a microchip it’s damn impressive considering the technology involved and the requirements it’s fulfilling. It’s amazing that we can now build devices that can produce ultra high vacuums smaller than a hotel minibar, and design systems that are capable of active cooling down to <1K without the use of any cryogenic refrigeration at all.
