Researchers Created 'Quantum Artificial Life' For the First Time (vice.com) 55

From a report: For the first time, an international team of researchers has used a quantum computer to create artificial life -- a simulation of living organisms that scientists can use to understand life at the level of whole populations all the way down to cellular interactions. With the quantum computer, individual living organisms represented at a microscopic level with superconducting qubits were made to "mate," interact with their environment, and "die" to model some of the major factors that influence evolution. The new research, published in Scientific Reports on Thursday, is a breakthrough that may eventually help answer the question of whether the origin of life can be explained by quantum mechanics, a theory of physics that describes the universe in terms of the interactions between subatomic particles. Modeling quantum artificial life is a new approach to one of the most vexing questions in science: How does life emerge from inert matter, such as the "primordial soup" of organic molecules that once existed on Earth?

    Incredible! :)

    • I call it cranking a steamer. The steam is strong on this one. I think there are more chaotic fluctuations in the poo steam than 5 cubits could model. And my life is profoundly influences by the beauty of that steam. I really don't think they can model life.

    Seriously, this is getting utterly ridiculous and not in any funny sense. That whole "quantum computing" thing is nonsense, get over it. And stop to find "new" applications that nobody needs and that work better on a classical computer anyways.

        As opposed to produce or perish?

        A university researcher's job is just as "real" as anyone else's. There are deadlines, budgets, evaluations, deliverables, conferences, reports, meetings, and so on.

        It's not easy to get a job doing university research. The pay is low compared to industry. People do it for the love of knowledge more than for the money.

      Quantum blockchain AI even.

    • As far as I can see, one class of problems where quantum computers can be useful, if they can be gotten to work, is in cracking encryption. Encryption can be, and is, crafted such that conventional deterministic solutions take impractical amounts of time. In principle, quantum computers can crack such encryption quite quickly. Testing to see if the quantum solution is correct -- it won't always be due to "leakage" of the correct answer out of the system -- is trivial. If you don't get a good answer, you

        Not even that. For block-ciphers, a working QC halves the key-length. That means AES-256 is not breakable with a QC in this universe and even AES-128 may be secure due to the extreme effort needed. That is for a known-plaintext attack. For things like RSA, you need to be able to put in the whole problem in one go. That means a huge number of entangled qbits, which may just be infeasible.

        So no, I doubt even this use-case will materialize.

      • Cracking most of the current asymmetric ciphers. When it comes to symmetric ciphers, quantum computing does indeed help, but it is trivial to enhance existing ciphers so that they become resistant to QC. As for asymmetric ciphers there already are QC-resistant schemes. By the time sufficiently capable QC becomes available (if it ever does) it will probably be a matter of little more than throwing a switch to transition to such schemes.

    This...is technobabble.

    Insofar as life started by bootstrapping from inanimate complex molecules, it isn't a difficult concept, and requires discrete units of atoms and molecules with real properties.

    There's nothing directly quantum required as life is all about chemistry at a very gross scale above the quantum.

    • My opinion also. The early Earth apparently had liquid water although it's unclear quite how since the sun was, in principle, quite dim back then. There are numerous known mechanisms for producing organic compounds if there is nothing around to eat them. Presumably self replicating organic compounds will eventually appear by pure chance if a complex organic soup sits around long enough. And life as we know it eventually evolved.

      The details are quite hazy and seem likely to remain hazy for decades or may

      I mostly agree that the article is technobabble (we've known about dynamic programming for a long time, and there's nothing quantum about it). Cells are indeed just a mass of molecules arranged in a certain way so that they can perform reactions and reproduce.

      However, I think that some of those chemical reactions are helped by quantum effects (I vaguely remember that mitochondria, in particular, due to their geometric configuration, "use" quantum effects to speed up their energy production beyond normal che

  • This was done with five noisy qubits. Everything that such a chip can do can be simulated at much higher quality on classical machines. Five quibits you could even simulate on your cell phone.

    I am running a start-up that is exploring what kind of use you can get out of near term noisy quantum computers (50 qubits and beyond).
