Iodine in water ionized on the picosecond scale, by laser pulse.
Would be mildly surprised if that didn't happen that fast. I guess the interesting twist is that the medium is flowing liquid.
How long does this state last? If one were to, say, write a series of bits into the upstream side of the flow, how many such bits could you recover downstream? The potential I see here is possibly a delay line for THz band signals, not so much the basis for logic for a 1000GHz CPU. But delay lines are darned useful things.
- vlovich123 4y agoIt’s been a while since I did circuits. What are delay lines used for?
- jacquesm 4y agoStorage, synchronization and signal recovery off the top of my head.
- surfpel 4y agoIn RF, delay can be used to attenuate signals. So filtering of signals.
- ajb 4y agoEarly computers used delay lines as memory https://en.wikipedia.org/wiki/Delay-line_memory https://en.wikipedia.org/wiki/Delay-line_memory
- evancox100 4y agoAlso sometimes you may want to apply skew/deskew to signals, finely tune the arrival time of two or more signals, etc.
