back to article If you're worried that quantum computers will crack your crypto, don't be – at least, not for a decade or so. Here's why

Quantum computing has been portrayed as a threat to current encryption schemes, but the ability of finicky vaporware to overthrow the current security regime looks like it's massively overstated. Richard Evers, cryptographer for a Canadian security biz called Kryptera, argues that media coverage and corporate pronouncements …

      So, as I'm using Rot13 twice, I'm safe for two decades?

    Spooky Military projects indeed, with pioneering test pilots in Live Operational Virtual Environments for phantom phormed futures and trading places aplenty.

    And as already correctly said, once pioneering crash test dummies prove prospecting promise in present projects and hush slush puppies survive then announcing such seems perfectly possible for future spread bet market revitalising revenue.

      QUB (CSIT) have also been tested for fitness in future purpose, CT., via the Augmented Virtual Reality FieldCraft vessel sent to a faculty member/leader, 15 Nov 2017 at 1433hrs.

      The Utility therein outlined are for anybody and everybody, although not able to be enabled by just anybody for everything.

        I dont know whether to stand and salute to that response amFM, or respond with a nautucal reply, just when I believe I have an understanding of past and present subject matters, extraordinary exponential learning lessons abound.

        One shall deem such to be a positively positive poseidon trident tribulation however and await the future relevant revelations which is all one can do :-)

    Intentionally fake news

    I'm sure that:

    1.you are stupid

    2. You are paid by NSA or other entities to calm peoples that they are secure by RSA or elyptic curves

    3.Shorr is OUTDATED and not optimal algorhytm, and nobody will use it in real life. There much more advanced ways to break RSA with quantum computer and its 5 years (max) away.

    4.you are very stupid and should stop writing on high tech themes.

    The only way to keep a secret is to kill the other guy that knows it.

      And what secrets would they be?, a secret is only a secret if deemed to be so.

      Everyone has the right to write, discuss, and profit from extraordinary events, discoveries or ideas, the issue becomes contemptuous when others seek to supress such for their own enrichment.

      As for killing such would not necessarily extinguish such should contingencies for such an event be expected and therefore the event of such would possibly result in an/others to release such contingency event/s.

      Notwithstanding that killing/conspiracy to kill or otherwise is unlawful, however as society drifts further and far right, a resurgence of history repeating itself in the worst ways is hardly suprising.

      Simple answer to sinister secrets is to pay up to shut up as they say, simples.

    Even if quantum computers would be able to break in next few years, I think it's safe to believe the security will be a step ahead just in case

    A thought

    Cracking RSA-2048 may be unrealistic. A lower hanging fruit would be to tell if a file is encrypted or just overwritten.

    From the article: "IBM's Q System gated quantum computer currently tops out at 20 qubits; it's been testing 50 qubit system. Intel has a 49 qubit machine and Google has a 72 qubit device."

    So, just add them all together via fibre-optic connections and you have a 191-cubit cluster-box. Ask the Chinese nicely and you may double this or more. Then just keep adding on boxes.

    No? Quantum doesn't work that way? Well, I never did expect the cosmos to be fair. :)

    So, a CRQC could not be possible by 2026 but might be possible by 2036?

    Isn't that sort of what they said about commercial fusion power? That we'd have it in fifty-some years? And haven't they been saying that for seventy-some years?

    Robotic vision. Household robots that are *useful*. True artificial *intelligence*, instead of a look-up table, decision tree and sorting scheme [no, *I* don't know what "intelligence" is, either :) ]. All "possible within the next decade" for decades.

    *Hyperdrive* is "possible". Anti-gravity is "possible" [both for certain values of the term].

    A CRQC may be "possible" but, just like the fabled tachyon, it may never be found nor made.

    Still, it keeps the spies occupied and the economy running which is no bad thing and basic research always eventually pays off in weird ways so there's that, too.

    But I have the nagging suspicion, totally uninformed guesswork though it is, that QC is a self-limiting thingy that eventually hits the wall of "just can't be done in this universe, pal". I don't know whether cluster-boxing it would help but I suspect that diminishing returns will be seen in our present approaches.

    Sort of like fusion.

    "Power too cheap to meter." Yeah, have you *seen* my bills? :)
