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 …

We present a theory of electronic properties of a quadruple quantum dot molecule (QQD)
which focuses on geometry, chirality, and electron–electron interactions. The QQD is …

We present a theory of electronic properties and the spin-blockade phenomena in a gated
linear triple quantum dot. Quadruple points where four different charge configurations are on …

Three-spin interactions in three-qubit systems at thermal equilibrium can be used for simple
and efficient creation of maximally entangled states. We do not require set of gates to …

Correlations between field-dependent planar spin configurations, degenerate frustration,
energy, vector κ z and scalar χ chiralities, spin canting, total, in-plane staggered and …

We consider the frustration, magnetochiral correlations, temperature and distortion
dependences of the vector and scalar chiralities, magnetization, and orbital angular …

Correlated spin configurations, magnetizations, frustration, vector κ¯ z and scalar χ¯
chiralities are considered for distorted V‾ 3,/Cu 3/anisotropic DM nanomagnets in transverse …

We present a theory of the electronic and optical properties of a charged artificial benzene
ring (ABR). The ABR is described by the extended Hubbard model solved using exact …

We propose an efficient three-qubit gate of singlet-triplet states in quantum dots based on
capacitative coupling. This scheme can be used to generate the maximally entangled …

The rotation behavior of the vector chirality κ, scalar chirality χ, and magnetization M in the
rotating magnetic field H 1 is considered for the V3 and Cu3 nanomagnets, in which the …
