Controlled exchange interaction for quantum logic operations with spin qubits in coupled quantum dots

S. Moskal, S. Bednarek, J. Adamowski

A two-electron system confined in two coupled semiconductor quantum dots is investigated as a candidate for performing quantum logic operations on spin qubits. We study different p…

Stark effect on the exciton spectra of vertically coupled quantum dots: horizontal field orientation and non-aligned dots

B. Szafran, F. M. Peeters, S. Bednarek

We study the effect of an electric-field on an electron-hole pair in an asymmetric system of vertically coupled self-assembled quantum dots taking into account their non-perfect al…

Magnetic-field-induced binding of few-electron systems in shallow quantum dots

B. Szafran, S. Bednarek, F. M. Peeters

Binding of few-electron systems in two-dimensional potential cavities in the presence of an external magnetic field is studied with the exact diagonalization approach. We demonstra…
