| Apr 6, 2022 at 12:43 | comment | added | Wag the mainstream media dog | @uhoh there are many applications of quantum effects beyond quantum computing. Gyroscopes using cold atoms/bose-einstein condensates have been experimented with, as they are rather similar in spirit to the optical fiber gyroscopes, but have potential for being more precise. | |
| Apr 6, 2022 at 12:31 | comment | added | uhoh | Cold atoms and structured light fields are one way to make qbits for quantum computing, and to study basic physics at low temperature, so I suppose that could feed into quantum computing, but then we'd have to figure out how quantum computing is "incredibly important for Australia's defense", or for any advanced country's defense for that matter?" again. :-) | |

| Apr 6, 2022 at 12:23 | comment | added | Wag the mainstream media dog | @uhoh Perhaps, I was a bit restrictive talking about semiconductor electronics only since many interesting things are also done with cold atoms and light. But the idea remains the same - the technology hits the quantum limit. | |
| Apr 6, 2022 at 12:23 | comment | added | uhoh | I understand, but I think Morrison is using a definition that's being used within government and defense circles in Australia as something that's new and different. Anyway, thank you for your answer! | |
| Apr 6, 2022 at 12:21 | comment | added | Wag the mainstream media dog | @uhoh everything in the world is quantum. Which is why I define what quantum means specificaly in this context: I have seen many talks in physics conferences in the last two decades starting with the Moore's law as the motivation of why we need quantum modeling of nanodevices. Up to now they are just classical circuits - note it does not apply specifically to quantum computing, but any electronic device. | |
| Apr 6, 2022 at 12:21 | comment | added | uhoh | My comments under that answer link to a few questions about quantum mechanics-based gyroscopes and accelerometers that will be much better than current inertial navigations systems and are right in line with everything else there, so I disagree that Morrison is referring to conventional CMOS-based electronics that's been around in one form or another since at least the late 1960's. | |
| Apr 6, 2022 at 12:17 | comment | added | uhoh | Although I was wrong about it referring to quantum computing, CDJB's answer which cites several quotes about quantum including that it's likely to be "quantum technologies for positioning, navigation, and timing. Vacuum tubes and specifically their cathode's thermionic emission is a quantum effect, so is the wavelength of the orange glow of the old neon light bulbs. | |
