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

Experimental and theoretical progress toward quantum computation with spins in quantum
dots (QDs) is reviewed, with particular focus on QDs formed in GaAs heterostructures, on …

Motion of electrons can influence their spins through a fundamental effect called spin–orbit
interaction. This interaction provides a way to control spins electrically and thus lies at the …

We analyze a quantum walk on a bipartite one-dimensional lattice, in which the particle can
decay whenever it visits one of the two sublattices. The corresponding non-Hermitian tight …

We report on conductance measurements in carbon nanotube based double quantum dots
connected to two normal electrodes and a central superconducting finger. By operating our …

A double quantum dot in the few-electron regime is achieved using local gating in an InSb
nanowire. The spectrum of two-electron eigenstates is investigated using electric dipole spin …

One proposal for a solid-state-based quantum bit (qubit) is to control coupled electron spins
on adjacent semiconductor quantum dots,. Most experiments have focused on quantum dots …

Because of the strong spin-orbit interaction in indium antimonide, orbital motion and spin are
no longer separated. This enables fast manipulation of qubit states by means of microwave …

For coherent electron spins, hyperfine coupling to nuclei in the host material can either be a
dominant source of unwanted spin decoherence,, or, if controlled effectively, a resource …

Understanding how the orbital motion of electrons is coupled to the spin degree of freedom
in nanoscale systems is central for applications in spin-based electronics and quantum …
