Electron spin qubits in silicon, whether in quantum dots or in donor atoms, have long been
considered attractive qubits for the implementation of a quantum computer because of …

Recent progresses in quantum dots technology allow fundamental studies of single donors
in various semiconductor nanostructures. For the prospect of applications figures of merits …

Two-electron states bound to donors in silicon are important for both two-qubit gates and
spin readout. We present a full configuration interaction technique in the atomistic tight …

The ability to control single dopants in solid-state devices has opened the way towards
reliable quantum computation schemes. In this perspective it is essential to understand the …

My Ph. D thesis brings together the highlights of the History of Nanotechnology (1950-2022)
to the present day. As this time-span is well documented, I based my three-year long …

Control of coupling of dopant atoms in silicon nanostructures is a fundamental challenge for
dopant-based applications. However, it is difficult to find systems of only a few dopants that …

Due to the constant size reduction, single-donor-based nanowire transistors receive an
increasing interest from the semi-conductor industry. In this work we theoretically investigate …

We investigate a hybrid metallic island/single dopant electron pump based on fully depleted
silicon-on-insulator technology. Electron transfer between the central metallic island and the …

We describe the first implementation of a coupled atom transistor where two shallow donors
(P or As) are implanted in a nanoscale silicon nanowire and their electronic levels are …

Solid-state platforms are promising candidates for future quantum computers. Recent
advances in solid-state nano-electronics have enabled precise control of individual atoms at …
