The study investigates coherent manipulation of electron spin in silicon

Electrons in silicon expertise coupling between their spin (up and down arrows) and valley states (blue and pink orbitals). Within the presence of a DC voltage (blue glow) the electron can bear coherent spin-valley oscillation. Picture credit score: Mike Osadcio. In recent times, many physicists and laptop scientists have been engaged on quantum computing applied … Read more

Where is physics headed (and how far are we getting there)?

The long run belongs to those that put together for it, because the scientists who petition federal companies like NASA and the Division of Vitality to fund analysis know nicely. Costly devices comparable to an area telescope or particle accelerator can price as much as $10 billion. And so this previous June, the physics neighborhood … Read more
