Optical Read-Out and Initialization of an Electron Spin in a Single Quantum Dot

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/21816We describe theoretically the resonant optical excitation of a trion with circularly polarized light and discuss how this trion permits the read-out of a single electron spin through a recycling transition. Optical pumping through combination of circularly polarized optical $π$--pulses with permanent or $π$-- pulsed transverse magnetic fields suggests feasible protocols for spin initialization.Materials ScienceOptical Read-Out and Initialization of an Electron Spin in a Single Quantum Dottext
