Phys. Rev. Lett. 83, 3912–3915 (1999)Interacting Two-Electron Model of a Coherent Quantum-Dot Single-Electron TurnstileReceived 8 March 1999; published in the issue dated 8 November 1999 We show how coherent single-electron turnstile action in a picosecond time scale can be achieved with high probability in a triple-well semiconductor structure by means of an applied time-dependent, long-wavelength electric field. We demonstrate the turnstile behavior by studying the exact temporal evolution of two electrons, including their Coulomb interaction, and considering both triplet and singlet states. © 1999 The American Physical Society URL:
