    What changed
    What the research demonstrates
    Previously

    The University of Chicago confirms Bluefors' second Chicago lab and a service model giving outside organizations access to cryogenic measurements. This establishes an operating infrastructure offering, complementing Bluefors' documented refrigerator product family.

    Now

    The University of Chicago confirms Bluefors’ second Chicago lab and its cryogenic measurement access model. For purchased hardware, Bluefors’ LD450/LD450sl technical table specifies 450 µW of guaranteed cooling power at 100 mK at the experimental flange outside the mixing chamber. This is an infrastructure specification, not a processor benchmark.

    What remains uncertain
    Previously

    Cooling power, wiring capacity and base temperature describe infrastructure. They do not establish the fidelity, useful qubit count or computational performance of a processor placed inside it.

    Now

    The cooling figure applies to the named model, measurement location and temperature. Published cooldown time uses an empty system with standard experimental space and shields; wiring and active loads require a separate thermal budget. These specifications do not establish processor fidelity or computational performance.

Recorded dates use UTC and show when QubitWire saved the comparison. Review dates show the evidence check; neither is a new claim about when the underlying event happened. This view preserves the original research and assessment methodology.
