Testing Bell's inequality with ballistic electrons in semiconductors
Abstract
We propose an experiment to test Bell's inequality violation in condensedmatter physics. We show how to generate, manipulate, and detect entangled states using ballistic electrons in Coulombcoupled semiconductor quantum wires. Due to its simplicity (only five gates are required to prepare entangled states and to test Bell's inequality), the proposed semiconductorbased scheme can be implemented with currently available technology. Moreover, its basic ingredients may play a role towards largescale quantuminformation processing in solidstate devices.
