Quantum Computers Just Made Scientists Very Uncomfortable

Fexl | June 8, 2026



The deeper questions are still wide open. We don’t know whether the spacetime we live in is fundamentally holographic, the way the maths sometimes suggests. We don’t know whether our universe is sitting in a “false vacuum”, waiting for a bubble to form somewhere in the dark and undo everything. We don’t know whether the next generation of quantum simulations will give us actual answers to those questions, or whether they’ll give us more artefacts dressed up as discoveries.

What we do know is that somewhere in Santa Barbara, a dilution refrigerator is humming with nine qubits inside it. Somewhere in Jülich, a different fridge is humming with 5,564 qubits inside it. In both places, physicists are doing something nobody has tried before. They are using quantum systems to ask the universe questions that have never been asked in a lab.

    So at Abosolute Zero atoms stop moving , right? If atoms stop moving what would be left , nothing would be left but a void , not even dust because isn't dust made of atoms ? Anyone care to explain that ?

    The qubit never left the silicon chip and the chip never warped gravity. It was a neat demonstration of quantum routing. But the "black hole" was just a mathematical analogy that was pushed way too far in the press releases.

    Well as a turd kicking layman I'd reckon the if ya put more horsepower (that AI stuff) to it ye'll get some answers quicker than if ya all tangled up in yer particles an holes. I ain't got the time an I'm runnin outta the space so I'll have to sign off here an cut some wood its gettin a trifle chilly.

    Funny how they always show the refrigerator and then call that the quantum computer.
    Proper quantum computing doesn't need special temperatures, as it is based on photonics.

    It's quite simple. It's a simulation of gravity. But that's what you'd expect if the universe was a holographic universe and higher dimensional projection

    I wonder if some of this is related to 4th, 5th, 6th etc dimensions where we could traverse spacetime at will as easily as we traverse our immediate space..

    I'm fine with mother nature hitting the quick format option,,,,,
    As long as the bubble arrives before my in-laws for the holidays.
