Classical-to-quantum crossover in electron on-demand emission

Kashcheyevs, Vyacheslavs and Samuelsson, Peter LU (2017) In Physical Review B 95(24).
Abstract

Emergence of a classical particle trajectory concept from the full quantum description is a key feature of quantum mechanics. Recent progress of solid-state on-demand sources has brought single-electron manipulation into the quantum regime; however, the quantum-to-classical crossover remains unprobed. Here we describe theoretically a mechanism for generating single-electron wave packets by tunneling from a driven localized state, and we show how to tune the degree of quantumness. Applying our theory to existing on-demand sources, we demonstrate the feasibility of an experimental investigation of quantum-to-classical crossover for single electrons, and we open up yet unexplored potential for few-electron quantum technology devices.
