Charge and spin coherent control in semiconductor quantum dot arrays

Controlling electron spins coherently in larger and larger quantum dot arrays is a prerequisite for the development of electron spin-based quantum processors. We will review our effort to control the charge and spin degrees of freedom of individual electrons in 2D arrays up to 9 tunnel-coupled semiconductor quantum dots. Procedures for deterministic filling, spin initialization, spin readout, spin manipulation and spin transfer and consideration for spin dynamics in the array will be discussed.
