The time-varying electric field, of single GHz frequency, perpendicular to the quantum wire, is used to induce the 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 the high fidelity all-electrical electron-spin initialization or readout in the spin-based quantum computer. In contrast to other spin initialization methods, our technique can be performed adiabatically without increase in the energy of the electron. Our simulations are supported by a realistic self-consistent time-dependent Poisson-Schroedinger calculations.", "revisions": [ { "version": "v1", "updated": "2020-09-25T21:16:18.000Z" } ], "analyses": { "keywords": [ "rashba spin-orbit interaction", "spin-selective resonant tunneling", "semiconductor nanowire", "realistic self-consistent time-dependent poisson-schroedinger calculations", "high fidelity all-electrical electron-spin initialization" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
