Adjustment in spin qubit design increases both its speed and its coherence time simultaneously, enabling more powerful quantum computers

"overcomes trade-off of qubit: need to be isolated from its environment to reduce decoherence/ need to be driven as fast as possible (analogy: classical bits' clocking) requiring strong interaction with environment... exploits certain kind of spin-orbit coupling: influencing how accelerator driving qubit reacts/ reducing qubit's sensitivity to environmental disturbance... 4X increased qubit coherence time, 3X faster drive, relatively warm 1.5°K instead of <100°mK requiring less energy/ works without need for rare helium-3"
