    > developed what we now call “magic state cultivation.”

    Somehow I can't help but read that phrase as a translated Wuxia [0] thing.

    "It was then that the Non-Observing Sage secluded himself in the clan datacenter to focus on magic state cultivation. Half a year later, he emerged having mastered Rosen-Bridge Crossing Under Plum Blossoms."

    I really wish someone eventually understands this so they could explain it to me in the comments

      It's kinda like magic numbers in a normal numerical algorithm. The issue is, the constants ('states') you need in some quantum computer themselves require some level of quantum computing to generate (in this case, iteratively 'cultivate'). In a normal computer you could read constants from the code, but that isn't possible here. You have to bootstrap the necessary quantum states from your non-quantum problem, and that needs to be efficient or else why did you build a quantum computer.

    The paper: "Magic state cultivation on a superconducting quantum processor" https://arxiv.org/abs/2512.13908 (Dec 2025)

    I love that the researcher in the video is just hanging out in her living room and holding her cat while recording her portion of the explainer
