Let me know when they start cracking hashes…


What will come first? [ ] Quantum Computers [ ] Fusion [ ] Half Life 2 [ ] GRR Martins next book


Okay so let me break down a few reasons why no one reading this needs to worry anytime ever about their stuff being cracked by a quantum computer. 1. Quantum Computers need a Superconductor to work, and not just any Superconductor, but one locked into a finite state and stabilized. 2. Currently to do this we have to basically cool the material down to very very very close to absolute zero. **If we ever figure out a way to achieve this at more reasonable temperatures, Quantum Computers aren’t the only thing this tech applies to.** Most of human life as we know it would fundamentally change if we can figure out a way to lock in super conductors at reasonable temps (and this isnt just being a super conductor, its a **stable** super conductor) 3. This process takes **several days** to perform, for *one* calculation. You heard me. And 99% of that time is that whole “cooling it down to almost absolute zero” part I mentioned above, as well as trial and error. See what happens is they cool it down annnd… nope it failed, try again. Repeat several times til it locks in right. Even if you get it on the first try, it will take easily 1-2 days for *one* calc. And there’s not much we can do to speed it up because its literally just sitting around waiting for it to get cold. 4. And to **keep** it that cold so it works, the thing needs to sit in a giant room with multiple layers of protection, cooling, heat sinks, you name it. A single Quantum Computer unit takes up an entire room, and it needs to be a Clean Room, everyone in suits. 5. And by the way, the cost to have a couple engineers run the thing, all the cooling liquid, the mountains of electricity, the equipment… Each calculation costs a small fortune to simply just run it. 6. Modern encryption algorithms would require a QPU several billion times more powerful than what we have right now. And if we just bump up the tier of encryption people use on basic stuff one tick, just a ever so slight bump of the knob up, it becomes several billion *times* more of a requirement yet again. You go from needing a couple billion qubits to a couple billion *billion* qubits, with just a nudge of encryption tier up, just like that. So for perspective now: Imagine if it took several days and fifty thousand dollars to hack **one** encrypted item, like, **one** email, *and* that email has to use an *extremely* outdated form of encryption from like, 20+ years ago. And we have millions and millions of qubits to work with (as opposed to the, what are we at, like 200 now on the most advanced QPU? Did we hit 400 yet?) Then I mean yep, you can do that, sure hope that email was worth the 50K it cost to crack. And I mean, hey, if its like, super critical information conferred between some politician and someone else 20 years ago that matters now… Maybe it could be. But no one is gonna drop 50K on cracking your portable hard drive full of ~~porn~~ “family photos”


At this point I think the media has overrun the word “breakthrough”. If every advancement is a breakthrough, none of them are.


My concern with technology like this is it will be monopolized by the rich only to be used to make money off the rest instead of solving important questions like: The Answer to the Ultimate Question of Life, the Universe, and Everything.
