@TindrasGrove@infosec.exchange @nieldk@infosec.exchange @DaveMWilburn@infosec.exchange @gvwilson@mastodon.social it's similar with the asterisk that you're probably also administering or depending on some kind of cryogenic plant as well, at least for the stuff that's in vogue. There *is* a lot of variety in what hardware is theoretically possible or realized on a lab bench and some of that isn't at cryogenic temps, but in terms of stuff that's anywhere close to "administration" by someone who is not a research scientist my understanding is that it's all gonna have a cryo component.

@SnoopJ@hachyderm.io @TindrasGrove@infosec.exchange @nieldk@infosec.exchange @DaveMWilburn@infosec.exchange @gvwilson@mastodon.social All quantum computers will need a cryo component at least for the detector. Unless there’s a fundamental change in how we are able to observe quantum states with enough certainty to use the resulting information, at least the detector needs to be super-chilled. Some systems require more cryogenics than others and some at different levels compared to others. Whether miliKelvin or sub-miliKelvin temperatures are needed depends on the materials and devices that work for the system. It will be much more like a specialized GPU (a QPU perhaps) compared to a CPU though. “Quantum advantage” isn’t universally straightforward, so a classical CPU will likely be orchestrating the computation and the interaction with the QPU, setting up the inputs and interpreting the outputs. Possible QPUs will vary wildly depending on the architecture and error correction ability
