Triplet-assisted leakage during singlet-triplet qubit readout with a quantum point contact
Karol Kawa
Quantum point contact readout theory for singlet-triplet qubits in a lateral double quantum dot is extended by including tunneling of triplet configurations into a higher-energy le…

Diffusion of excitation and power-law localization in long-range-coupled strongly disordered systems
Karol Kawa, Paweł Machnikowski
We investigate diffusion of excitation in one- and two-dimensional lattices with random on-site energies and deterministic long-range couplings (hopping) inversely proportional to…

Spin-orbit-induced hole spin relaxation in a quantum dot molecule: the effect of - coupling
Karol Kawa, Paweł Machnikowski
We study the effect of the coupling between the hole shell of one quantum dot and the shell in the other dot forming a quantum dot molecule on the spin relaxation between t…
