M. Fernando Gonzalez-Zalba
There is a wide range of physical systems being actively explored to represent qubits. Those based on silicon benefit from a number of intrinsic advantages (such as long coherence times) combined with the scalability of a solid-state approach and the extensive industrial infrastructure of silicon transistor technology. Nanodevices based on spins in silicon have demonstrated a number of key recent advantages, including high-fidelity single-spin readout. Such measurements show the potential of silicon-based qubits, however, the milestone of demonstrating qubits in devices fabricated by industrial CMOS processes remains to be demonstrated.In this talk, I will present recent results on split-gate CMOS transistors that demonstrate the possibility to store, transfer and read single electron spins, all milestones towards the first experimental demonstration of an all CMOS qubit.Finally, I will conclude my talk showing the road map towards a full scalable integration of this technology. From the single qubit CMOS cell, towards the line and the surface codearchitectures.
