Optimizing spin-orbit splittings in InSb Majorana nanowires
Semiconductor-superconductor heterostructures represent a promising platform for the detection of Majorana zero modes and subsequently the processing of quantum information using their exotic non-Abelian statistics. Theoretical modeling of such low-dimensional heterostructures is generally based on phenomenological effective models. However, a more microscopic understanding of the band structur...
متن کاملPhonon modulation of the spin-orbit interaction as a spin relaxation mechanism in InSb quantum dots
We calculate the spin relaxation rates in a parabolic InSb quantum dots due to the spin interaction with acoustical phonons. We considered the deformation potential mechanism as the dominant electron-phonon coupling in the Pavlov-Firsov spin-phonon Hamiltonian. By studying suitable choices of magnetic field and lateral dot size, we determine regions where the spin relaxation rates can be practi...

متن کاملSpin-orbit induced spin-qubit control in nanowires
We elaborate on a number of issues concerning our recent proposal for spin-qubit manipulation in nanowires using the spin-orbit coupling. We discuss the experimental status and describe in further detail the scheme for single-qubit rotations. We present a derivation of the effective two-qubit coupling which can be extended to higher orders in the Coulomb interaction. The analytic expression for...
متن کاملspin–orbit interaction
We have measured the hyperfine structure of mutually perturbing rovibrational levels of the 1sbd P0 and 2sAd S states of the NaK molecule, using the perturbation-facilitated optical-optical double resonance method with copropagating lasers. The unperturbed 1sbd P0 levels are split into four hyperfine components by the Fermi contact interaction bFI ·S. Mixing between the 1sbd P0 and 2sAd S level...
