back to article Businesses brace for quantum computing disruption by end of decade

While business leaders expect quantum computing to play a significant role in industry by 2030, some experts don't believe the tech is going to be ready for production deployment in the near future. The findings, from a survey titled "2022 Quantum Readiness" commissioned by consultancy EY, refer to UK businesses, although it …

    Now that Crypto has tanked...

    lo and behold... another bandwagon/tech bubble comes along to make the consultant (who know zip) a tonne of money.

      Before it makes it to consultant you have a chain of agencies, then a fee payer, consultant's company and finally a consultant, likely getting less than 25-50% of the "tonne of money".

        don't leave out certification and training they want their chunk too

    And what is the basis for these business leaders and executives' beliefs? Deep technical knowledge and judgement or FOMO?'

      The only thing I know for sure is that this isn't based on a dodgy survey trying to make something appear much more popular than it really is!!

    You can say when it will be available or how much it will cost, but not both.

      It will be soon, be cheap or be effective.

    I'm still waiting for my industry to adopt relational databases... but sure, Quantum. Once more unto the hype curve dear friends, once more.

    > Organizations may want to address threats like this by taking steps such as ... increasing the key sizes for current crypto algorithms like AES

    And how long is going from 1024 to 4096 bits supposed to gain you once QC come online? A year, a month or a week?

    1. devjoe

      Quite long.

      AES256 will be unbreakable under QC for at least another 30 years (assuming mainstream QC comes online tonight).

      What QC does for bruteforce is it allows you to brute force an n-bit key in 2^(n/2) time rather than 2^n time.

      That means AES128 would be breakable, because that would be 2^64 work which is doable (assuming large scale reliable QC is available).

      But AES256 would still be completely unbreakable, becuase 2^128 is unbreakable today for at least another 30 years by any nation-state.

      So we'll be fine. Don't worry.

    Quantum computers require super cooled temperatures to operate and high levels of technical expertise. They are still experimental and have many obstacles to over come before they ever see even limited production or availability. Quantum physics is a strange beast that we have yet to come close to controlling. Looking well into 2100 if ever, 20 or 30 years is beyond optimistic. More in the realm of fantasy.

    Which will get here first?

    Quantum computing or fusion powerplants?

      Re: Which will get here first?

      Quantum computer controlled fusion power stations with linux desktops.

      Re: Which will get here first?

      well there have been proof of concept reactors for fusion for quite a while, usually of the Tokomak variety (but some using inertial confinement instead), since the 80's even.

      Still waiting on a "Hello, World?" example for quantum computing

    It's the same old thing over and over

    Without fail, every 5-10yrs there's a new 'must have tech that'll disrupt and advance the markets'

    Anyone remember when 'digital' was the new buzz word at the end of the 90's... everything went 'digital' which in most cases, meant companies slapping a tiny LCD on the same old crap to display the same info that it did before... But was now 'DIGITAL' and could be sold for much more... Quite how this was disrupting and advancing the market... no one has yet figured out.

    This last 5-6yrs it's been AI.... or to those of us with more than 2 brain cells... machine learning, a simple piece of software that attempts to 'guess' the correct answer... whilst artificial, it lacks actual intelligence... Much like the marketing twonks who push these buzz words.

    Now we're moving on to 'quantum'

    I'm bored... so very very bored of the bullshit.

    Ya know what would actually peak my interest.... Honesty in advertising for once. Because all of this bullshit only serves one purpose... to turn me off buying stuff.

      "Honesty in advertising"

      Volvo - they're boxy but they're safe

      Diet pills - they don't work but at least you get a free plant

      Jaguar - For men who like hand jobs

      I think these are all from a Dudley Moore film.........

        I remember that movie... from like 30yrs ago... He was in a mental health hospital with a load of others and got them to create 'honest advertisements' for his job... Probably saw it in the 90's at some point... never since.

        I just have a memory for useless movie trivia

    501 UK-based executives

    So, basically, the people that subscribe to Gartner Trends. The same ones that are anticipating the Metaverse.

    When you ask a bunch of clueless, overpaid, suits you get this kind of nonsense.

      Re: 501 UK-based executives

      501? I thought that was a game of darts. But then again maybe that's how they do surveys. I see you just threw a triple 19, that'll be «that respondents were "almost unanimous" in their belief that quantum computing will create a moderate or high level of disruption for their own organization, industry sector, and the broader economy in the next five years.»

    I am developing a Quantum SBC in a Raspberry Pi form factor. Look out for my Kickstarter campaign coming soon.

    Fuck me this shows ignorance

    81% of these "business leaders" think that quantum computing is going to disrupt their business within 7 years? How?

    It would be nice to know what businesses these "leaders" represent and why they think this will affect their particular businesses. i would also like to know why they think quantum computing will disrupt their businesses any more than advances in classical computing.

    I can understand this being applicable to, say high-frequency trading, but even then you have other constraints, such as your comms speed. Meteorological forecasting, yes. Perhaps flow analysis, for F1 cars say, but seriously: build a model and stick it in a wind tunnel. Plus QC may not really offer any advantage to this analysis anyway.

    For me, this is just another example of how little "business leaders" know about technology - and every large company is an IT company now, whether they understand that or not.

    Such explains why it is so incredibly expensive to price in relation to the incurred future costs and ongoing liabilities suffered if one does not engage with effective and efficient defence forces and cyber sources more than just expert and experienced in the genre of special paravirtualised operations.
