Harnessing Si CMOS technology for quantum information

Abstract

We present some recent progress towards the implementation of the basic building blocks of quantum information processing derived from a Si CMOS technology platform. In our approach, characterized by an emphasis on foundry compatibility in terms of processes and materials, the so-called qubits are encoded in the spin degree of freedom of gate-confined elementary charges. After introducing various qubit manipulation, coupling and readout schemes, we discuss some prospects for scalability, and in particular some potential advantages of the FDSOI technology.
