Entanglement in Spin Chains

Abstract

Semiconductor quantum dots are a promising platform for quantum simulation and computing. This chapter will review the fundamentals of semiconductor quantum dots and the Heisenberg exchange coupling that occurs between neighboring quantum dots. Despite directly coupling only nearest-neighbor quantum dots, exchange coupling underlies a great many approaches for quantum information processing, quantum state transfer, and the simulation of spin chain dynamics. This chapter will review recent progress and future work along these directions.
