@MartinJJ @mrman @Krez it's not marketing bullshit, it's perfectly consistent science although I agree absolute zero is likely impossible, there's problems such as vacuum energy and it boils down to how you define it
a friend's lab can actually cool atoms to negative values of absolute zero, but it's just a quirk of how you define it as temperature is meant to describe large numbers of molecules in a given container - this loses its meaning when you have only a few atoms bopping about in a vacuum
what is bullshit is the idea that a system like this can scale up to millions of qubits - even if you could do that in the near term (the bigger you make them, the more heat up and the harder they are to cool) the fact remains that the nature of quantum systems means you need huge error correction - like hundreds of qubits to a make a reliable qubit to run calculations on
it's like claiming you'll soon have millions of employees but fail to mention that the employees are in fact highly trained mice that require several hundred to run a human sized robot
and with that I'd like to thank you for your courage and have dinner
@skells @mrman @Krez
It's indeed something like skells suggests, basically marketing BS. Probably not even that low. In Absolute Zero (Kelvin) all atoms would stop and everything most likely would disintegrate or create new chemical structures or something like that. Technically it would be impossible to reach it as it would require infinite resources. I think they already came really close before in several experiments.
