Control of electron spin at spin-resolved quantum Hall edges

Magnetic field and spin-orbit interaction (SOI) are representative freedoms that can be entangled to electron spins. In experiments, while magnetic field strong enough for the control of spin is difficult to be localized onto the area for single spins such as quantum dots, the orbit can be localized to narrow regions with mesoscopic structures. Hence for quantum information manipulation borne by electron spins, the control through SOI has an advantage in that sense.
