Abstract
We consider a single electron confined within a quantum wire in a system of two electrostatically induced quantum dots defined by nearby gates. A time-varying electric field, of single gigahertz frequency, perpendicular to the quantum wire, is used to induce Rashba coupling and enable spin-dependent resonant tunneling of the electron between two adjacent potential wells with fidelity over 99.5%. This effect can be used for high-fidelity all-electric electron-spin initialization or readout in a spin-based quantum computer. In contrast to other spin-initialization methods, our technique can be performed adiabatically without an increase in the energy of the electron. Our simulations are supported by realistic self-consistent time-dependent Poisson-Schrödinger calculations.
