>>12584878>You have to chill the computerOnly the superconducting ones. Photonic chips for example exist and work at room temperature.
>>12585145That, plus quantum communication, solving linear equation systems (engineering, medicine, anything really), optimization (also pretty much anything), gaming (world generation), quantum chemistry, there are a lot of things shown to work already.
I give it ten years max, depending on whether China starts a war.
