Making the clock 1,000,000 times faster would mean the silicon would be 1,000,000 times shorter (in each dimension) so I guess such designs would support some super high clock rates for some specialist applications for small gate arrays, but for general purpose computing, hmm, i'm not so sure.
- seiferteric 4y agoYa the article focuses on computing but I think it could enable totally new electronic devices like frequency/phase controllable leds, light field displays and cameras, ultra fast ir based wifi etc...
- zardo 4y agoI think that's fast enough for gravity gradiometry on a chip.
- zardo 4y agoThat is, by just putting a clock on each corner and counting their relative ticks.
- skykooler 4y agoI could see this potentially allowing VLB interferometry for optical frequencies, allowing even higher resolutions than the Event Horizon Telescope.

- kazinator 4y agoPropagation delay isn't purely about distance: it's about the time needed for the output to settle in reaction to inputs. That includes capacitive delays: containers of electrons having to fill up. Say we are talking about some gate with a 250 picosecond propagation delay. But light can travel 7.5 cm in that time; way, way larger than the chip on which that gate is found, let alone that gate itself. That tells you that the bottleneck in the gate isn't caused by the input-to-output distance, which is tiny.
