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 …

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 …

This article reviews the current status of spin dynamics in semiconductors which has
achieved much progress in the recent years due to the fast growing field of semiconductor …

The variational method complemented with the use of explicitly correlated Gaussian basis
functions is one of the most powerful approaches currently used for calculating the …

Tunnelling of material particles through a classically impenetrable barrier constitutes one of
the hallmark effects of quantum physics. When interactions between the particles compete …

We show that two-photon transport is strongly correlated in one-dimensional waveguide
coupled to a two-level system. The exact S matrix is constructed using a generalized Bethe …

Rapid coherent control of electron spin states is required for implementation of a spin-based
quantum processor. We demonstrated coherent control of electronic spin states in a double …

We demonstrate control of the electron number down to the last electron in tunable few-
electron quantum dots defined in catalytically grown InAs nanowires. Using low temperature …

Singlet-triplet spin blockade in a few-electron lateral double quantum dot is investigated
using simultaneous transport and charge-sensing measurements. Transport from the (1, 1) …

Investigations of emergent symmetry breaking phenomena occurring in small finite-size
systems are reviewed, with a focus on the strongly correlated regime of electrons in two …
