"controlling electron spin in silicon quantum dots... spin-valley coupling," which occurs when electrons in silicon quantum dots transition between different spin and valley states... apply voltage pulse to harness spin-valley coupling effect and manipulate spin and valley states, controlling electron spin... without the need of oscillating magnetic fields, which is a limitation of ESR," Nichol says. "This allows us a new pathway for using silicon quantum dots to manipulate information in quantum computers"
