    Is there any information about which QC groups if any are experimenting with using this in their setups?

    I found this from QCTech - one thing about Intel is they can make technology in chips that are for real situations - Quantum Computers needs to be real world for it to work

    But this is more advance than most people now days - including myself and others.

    How long can they keep qubits entangled at 4K and how many?

    Seems like quantum computing so far has been experiencing anti-Moore law - more qubits means exponentially increasing cost, size and energy consumption.

    Both superconducting and semiconductor quantum-dot qubits live at milliKelvin temperatures, but the challenge of integrating control electronics at those temperatures is that your total heat budget, for absolutely everything, is maybe ten or twenty microwatts. At most. So, most groups looking at active control schemes for multiplexing control and readout put the active electronics either at the 500 mK stage of the cryostat (heat budget: ~50 mW) or the 4 K stage (~1-2 W). You're still limited by the space and thermal constraints of running microwave lines down to the colder parts of the system (Google's Sycamore processor, of "quantum supremacy" fame, has a few hundred coaxes for their 53 qubits, to give an idea of scale), but at least you're not running quite so many lines up to room temperature.

    I say neigh on this being a good idea.

    I'm very certain whoever names their products is sitting on a 500-acre ranch in the middle of Montana and looks out the window to decide their next product name.

    What? Quantum computing?

    "Let's just stop with the technology, already!" Yeah, right.

    Horse Ridge? -_- Come on, they couldn't come up with more stupid name.
