ABSTRACT Spin-based electronics or spintronics relies on the ability to store, transport and manipulate electron spin polarization with great precision1,2,3,4. In its ultimate limit,

information is stored in the spin state of a single electron, at which point quantum information processing also becomes a possibility5,6. Here, we demonstrate the manipulation, transport

and readout of individual electron spins in a linear array of three semiconductor quantum dots. First, we demonstrate single-shot readout of three spins with fidelities of 97% on average,

using an approach analogous to the operation of a charge-coupled device (CCD)7. Next, we perform site-selective control of the three spins, thereby writing the content of each pixel of this

sensing. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to
