The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

Initialization, two-spin coherent manipulation, and readout of a three-spin qubit are
demonstrated using a few-electron triple quantum dot. The three-spin qubit is designed to …

The goal of this article is to review the progress of three-electron spin qubits from their
inception to the state of the art. We direct the main focus towards the exchange-only qubit …

Electrostatic confinement of charge carriers in bilayer graphene provides a unique platform
for carbon-based spin, charge, or exchange qubits. By exploiting the possibility to induce a …

Measurements are presented of a device designed to cool a 6 μ m 2 region of 2D electron
gas using quantum dots. Electrostatic effects are found to be significant in the device, and a …

Adiabatic techniques are known to allow for engineering quantum states with high fidelity.
This requirement is currently of large interest, as applications in quantum information require …

We experimentally investigate the charge (isospin) frustration induced by a geometrical
symmetry in a triangular triple quantum dot. We observe the ground-state charge …

The transport of quantum information between different nodes of a quantum device is among
the challenging functionalities of a quantum processor. In the context of spin qubits, this …

As an advanced quantum system, a three terminal triple quantum dot with one lead attached
to each dot allows us to simultaneously measure a transport along two different paths …
