  We present recent progress towards the implementation of a scalable quantum
processor based on fully-depleted silicon-on-insulator (FDSOI) technology. In
particular, we discuss an approach where the elementary bits of quantum
information - so-called qubits - are encoded in the spin degree of freedom of
gate-confined holes in p-type devices. We show how a hole-spin can be
efficiently manipulated by means of a microwave excitation applied to the
corresponding confining gate. The hole spin state can be read out and
reinitialized through a Pauli blockade mechanism. The studied devices are
derived from silicon nanowire field-effect transistors. We discuss their
prospects for scalability and, more broadly, the potential advantages of FDSOI
technology.
