Long-range exchange coupling for spin qubits

Invited

Abstract

To scale the arrays of single-electron quantum dots arrays it is necessary to realize long-range spin coupling. In the talk I will present our study of multielectron quantum dots and demonstrate they mediate exchange interaction. In addition I will discuss tunability of multielectron coupler and argue that it can also be used to transfer the electrons between non-neighboring dots.
