Carbon nanotubes are a versatile material in which many aspects of condensed matter
physics come together. Recent discoveries have uncovered new phenomena that …

Although electron spins in III–V semiconductor quantum dots have shown great promise as
qubits,,, hyperfine decoherence remains a major challenge in these materials. Group IV …

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 …

The manipulation and readout of spin qubits in quantum dots have been successfully
achieved using Pauli blockade, which forbids transitions between spin–triplet and spin …

We investigate a two-electron double quantum dot with both spin and valley degrees of
freedom as they occur in graphene, carbon nanotubes or silicon and regard the 16 …

Dynamical buildup of spin-singlet correlations between the two quantum dots is investigated
by means of the time-dependent numerical renormalization group method. By calculating …

We develop a theory of intervalley Coulomb scattering in semiconducting carbon-nanotube
quantum dots, taking into account the effects of curvature and chirality. Starting from the …

Motivated by a recent experiment [F. Pei, Nat. Nanotechnol. 7, 630 (2012) 1748-3387
10.1038/nnano. 2012.160], we theoretically study the Pauli blockade transport effect in a …

We study theoretically the return probability experiment, which is used to measure the
dephasing time T 2*, in a double quantum dot (DQD) in semiconducting carbon nanotubes …

This thesis describes experiments on quantum dots made by locally gating one-dimensional
quantum wires. The first experiment studies a double quantum dot device formed in a Ge/Si …
