      I believe you may have misread your own source.

      For example, the world’s fastest supercomputer, Frontier, draws 8 megawatts when it idles — a quantity that could simultaneously power thousands of homes

      If this was the basis for your saying this…

      several hundred supercomputer megaclusters and sucks more power than a thousand suburbs.

      … then you misread AND misstated.

      Misread: this “thousands of homes” energy use was in reference to Frontier, which is not a quantum computer but based on more conventional architecture, the kind the article goes on to say might eventually be improved upon by quantum computing. Eg:

      Consequently, experts are looking to new strategies that can rein in energy use while continuing to improve computing performance. One proposed solution: quantum computing.

      Misstated: “thousands of homes” != “thousands of suburbs.”

      A suburb is not a home but a a collection of homes, a region of a city even. See definition:

      an outlying part of a city or town. b. : a smaller community adjacent to or within commuting distance of a city. c. suburbs plural : the residential area on the outskirts of a city or large town.

      So in your zeal to make your point you demonized quantum computers, which could be a solution to the problem you’re ostensibly so concerned about, and in the process you misstated a metric by at least one order of magnitude.

      So yeah… I don’t know what to tell you. You really messed up here. Your problem is with LLMs and big compute, not necessarily quantum computers.

          But it is difficult to acquire here on earth.

          As uranium and thorium naturally decay underground, they produce some helium as well. That’s why you can literally make a helium mine. On earth it’s also a finite resource, because once released into the atmosphere, it will eventually escape the atmosphere and end up in space.

      Because that’s the cooling system required to run the thing. It requires more toxic coolant, that will eventually end up in the ocean, than several hundred supercomputer megaclusters and sucks more power than a thousand suburbs.

      Congrats on getting upvotes for this utter bullshit, none of which is substantiated in the article you linked.

      Edit- this was at +15 when I first saw it.

      I’m prepared to be proven wrong on this, as my exposure to quantum computer cooling systems has been super brief, but as far as I know there are no toxic coolants.

      The pre cooler is a Pulse Tube Refrigerator, and the main cooler is a Dilution Refrigerator. Those both use helium, and that stuff floats out into space. I doubt it’s going into the ocean. Here’s another article that talks about the operation.

      Like I said though, my exposure was brief. Unfortunately we didn’t land any projects with the supercomputer people 😞. I’m always down to learn more about niche topics though. Makes me super fun at parties. If you have good sources shoot them my way. I couldn’t find anything in my 5 ish minutes of web searching.

        Wrong. I breathed in some helium once and it made my voice all high pitched which threatened my fragile masculinity. Very toxic.

        (/s…)

        Never worked much with cryogenics, but the one thing I learned was to never get in an elevator with (large quantities of) liquid nitrogen — if the elevator stops it can displace the oxygen and that’s…kinda bad.

          Yeah, totes. Scentless non-toxic gases can still be deadly by merit of not being oxygen.

          The only recreational octave-shifting gas I indulge in is Sulfur Hexafluoride. Bolsters the ol’ baritone.

              I just looked it up and…

              SF6 has 23,500 times greater global warming potential (GWP) than CO2 as a greenhouse gas (over a 100-year time-frame) but exists in relatively minor concentrations in the atmosphere. Its concentration in Earth’s troposphere reached 11.50 parts per trillion (ppt) in October 2023, rising at 0.37 ppt/year.[8] The increase since 1980 is driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminium, and electronics manufacturing also hastened atmospheric growth.[9] The 1997 Kyoto Protocol, which came into force in 2005, is supposed to limit emissions of this gas. In a somewhat nebulous way it has been included as part of the carbon emission trading scheme. In some countries this has led to the defunction of entire industries.[10]

              Umm wtf? Why are we selling this stuff in compressed air cans ? Even methane is “only” 30x more potent than CO2 .

                3M made a great alternative I actually tried to get my company into, Novec 4710… But turns out they’ve stopped making it.

                The bitch about SF6 is that it’s so stable (as required, to resist high voltage electric breakdown) that it also lasts way, way long in the atmosphere.

                Yeah man, I don’t know. I think we need to just use less energy, as a species.

      A quantum computer using current technologies can’t scale to that size. Enormous advances over what is now currently possible would be required to get it to that number of qubits, and then the whole issue of cooling can be revisited.

      Wow, that is insane! But it’s also amazing that it has been able to solve problems that humans haven’t been able to solve in over 50 years.
