Spins in few-electron quantum dots
The canonical example of a quantum-mechanical two-level system is spin. The simplest picture of spin is a magnetic moment pointing up or down. The full quantum properties of spin become apparent in
Electron transport through double quantum dots
Electron transport experiments on two lateral quantum dots coupled in series are reviewed. An introduction to the charge stability diagram is given in terms of the electrochemical potentials of both
Signatures of Majorana Fermions in Hybrid Superconductor-Semiconductor Nanowire Devices
TLDR
Electrical measurements on indium antimonide nanowires contacted with one normal (gold) and one superconducting (niobium titanium nitride) electrode support the hypothesis of Majorana fermions in Nanowires coupled to superconductors.
Mesoscopic electron transport

Driven coherent oscillations of a single electron spin in a quantum dot
TLDR
The experimental realization of single electron spin rotations in a double quantum dot is reported, demonstrating the feasibility of operating single-electron spins in a quantum dot as quantum bits.
Few-electron quantum dots
We review some electron transport experiments on few-electron, vertical quantum dot devices. The measurement of current versus source–drain voltage and gate voltage is used as a spectroscopic tool to
Single-shot read-out of an individual electron spin in a quantum dot
TLDR
Electrical single-shot measurement of the state of an individual electron spin in a semiconductor quantum dot is demonstrated using spin-to-charge conversion of a single electron confined in the dot, and the single-electron charge is detected using a quantum point contact.
Spin–orbit qubit in a semiconductor nanowire
TLDR
The coherence times achieved here are sufficient for the conversion of an electronic qubit into a photon, which can serve as a flying qubit for long-distance quantum communication.
Electron Transport in Quantum Dots
The ongoing miniaturization of solid state devices often leads to the question: “How small can we make resistors, transistors, etc., without changing the way they work?” The question can be asked a
Quantum transport in carbon nanotubes
Carbon nanotubes are a versatile material in which many aspects of condensed matter physics come together. Recent discoveries have uncovered new phenomena that completely change our understanding of
