摘要

A method and nanodevice are introduced that allows us to rotate the single electron spin confined in a gated electrostatic InSb nanowire quantum dot. The proposed method does not require the application of any (oscillating or static) external magnetic fields. Our proposal instead employs spatial and time modulation of confining potential induced by electric gates, which, in turn leads to oscillating Rashba-type spin-orbit coupling. Moving electron back and forth in such a variable Rashba field allows for the realization of spin rotations around two different axes separately without using an external magnetic field. The results are supported by realistic three-dimensional time-dependent Poisson-Schrodinger calculations for systems and material parameters corresponding to experimentally accessible structures.
