“What’s More Advanced Than AI? Quantum AI Is the Next Leap Forward”

“… What is quantum computing?

Classical and quantum computing differ in several ways, one of which is processing.

Classical computing uses linear processing (step-by-step calculations),
while quantum uses parallel processing (simultaneous calculations).

Another difference is in the basic processing units they use.

Classical computers use bits as the smallest data unit (either a 0 or a 1).

Quantum computers use quantum bits, aka qubits, based on the laws of quantum mechanics.

Qubits can represent both 0 and 1 simultaneously thanks to a phenomenon called superposition.

Another property that quantum computers can leverage is entanglement.

It’s where two qubits are linked so that the state of one immediately influences the state of the other, no matter the distance.

Superposition and entanglement allow quantum computers to solve complex problems much faster than traditional computers.

Where classical computing can take weeks or even years to solve some problems, quantum computing reduces the timeframe for achievement to merely hours.
So why aren’t they mainstream?

Quantum computers, running on purpose-built quantum chips, are incredibly delicate and must be kept at amazingly low temperatures to work properly.

They’re massive and not yet practical for everyday use.

Still, companies like Intel, Google, IBM, and Microsoft are heavily invested in quantum computing, and the race is on to make it viable. …”

    have you tried using doggie treats?

    you can measure a sizable arc using qubits.

  3. Tom Kirkmanreplying to Bob S. Heath

    I tend to think of the current Quantum Computing mania as very much akin to the dotcom boom and subsequent bust, decades ago.

    Beware the hype. I remain *exceedingly skeptical* about quantum computing, but made it a point to not let my skepticism bleed through here.

    Long time readers of my posts are generally aware that I constantly poke fun at AI, since AI is not intelligent at all.

    =================

    The widespread excitement around generative AI, particularly large language models (LLMs) like ChatGPT, Gemini, Grok, and DeepSeek, is built on a fundamental misunderstanding. While these systems impress users with articulate responses and seemingly reasoned arguments, the truth is that what appears to be “reasoning” is nothing more than a sophisticated form of mimicry.

    These models aren’t searching for truth through facts and logical arguments—they’re predicting text based on patterns in the vast datasets they’re “trained” on.

    That’s not intelligence - and it isn’t reasoning. And if their “training” data is itself biased, then we’ve got real problems. ...

    I already did a Noah's Ark joke below, in reply to Patrick Devine :

    you can measure a sizable arc using qubits."

    Ken N. thanks for the additional information, presented in an easy to understand way.
