Personally I find quantum computers really impressive, and they havent been given its righteous hype.
I know they won’t be something everyone has in their house but it will greatly improve some services.
Yes, but, quantum TPM or TPU chips would allow for far more complex encryption. So you’d likely have a portiion of the SOC with a quantum bus or some other function.
However you’re correct that it’d take a seachange in computing for a qbit based OS
Strong, post quantum encryption doesn’t require quantum computers. It uses different mathematical objects (e.g. matrices)
True. However there is still a usecase. You could sign a cert for uefi much like a payment would. Useful for distributed compute.
