<< Dr. Sergey Danilin, (..) describes quantum control-the process of using chips like transmons to build quantum computers-by extending the "climbing a ladder" analogy. "To get a useful quantum system, you need to imagine climbing a ladder while holding a glass of water-it works if one does it smoothly, but if you do it too fast, the water spills. Certainly, this requires a special skill." (..) in the quantum world, the trick for climbing the ladder quickly without spilling any water is by carefully jumping two rungs at a time. >>
