Decoherence enhanced quantum measurement of a quantum dot spin qubit
Katarzyna Roszak, Łukasz Marcinowski, Paweł Machnikowski
We study the effect of phonons on a proposed scheme for the direct measurement of two-electron spin states in a double quantum dot by monitoring the the noise of the current flowin…
Energy transport and coherence properties of acoustic phonons generated by optical excitation of a quantum dot
D. Wigger, S. Lüker, D. E. Reiter +3
The energy transport of acoustic phonons generated by the optical excitation of a quantum dot as well as the coherence properties of these phonons are studied theoretically both fo…
Excitons in quantum dot molecules: Coulomb coupling, spin-orbit effects and phonon-induced line broadening
J. M. Daniels, P. Machnikowski, T. Kuhn
Excitonic states and the line shape of optical transitions in coupled quantum dots (quantum dot molecules) are studied theoretically. For a pair of electrically tunable, vertically…
Spin dynamics in p-doped semiconductor nanostructures subject to a magnetic field tilted from the Voigt geometry
K. Korzekwa, C. Gradl, M. Kugler +9
We develop a theoretical description of the spin dynamics of resident holes in a p-doped semiconductor quantum well (QW) subject to a magnetic field tilted from the Voigt geometry.…
Phonon influence on the measurement of spin states in double quantum dots using the quantum point contact
Łukasz Marcinowski, Katarzyna Roszak, Paweł Machnikowski +1
We study the influence of phonon scattering on the single-triplet measurement of two-electron spin states in a double quantum dot doped with two electrons. We point out that at low…
Double quantum dot in a quantum dash: optical properties
Piotr Kaczmarkiewicz, Paweł Machnikowski, Tilmann Kuhn
We study the optical properties of highly anisotropic quantum dot structures (quantum dashes) characterized by the presence of two trapping centers located along the structure. Suc…
