"precisely controlling single electrons (rather than magnetic fields) nestled in quantum dots that run logic gates... less bulky and requires fewer parts... based on the same CMOS technology as today’s computer industry making this method easier and faster to scale up and closer to goal of fabricating billions of qubits on a single chip"
