Phonon-induced Majorana Qubit Relaxation in Tunnel-Coupled Two-Island Topological Superconductors
Yang Song, S. Das Sarma
A Majorana-based qubit can form within the fermion parity subspace of a two-island topological superconductor setup consisting of four Majorana zero modes. We study the relaxation…
Spin-orbit coupling induced two-electron relaxation in silicon donor pairs
Yang Song, S. Das Sarma
We unravel theoretically a key intrinsic relaxation mechanism among the low-lying singlet and triplet donor-pair states in silicon, an important element in the fast-developing fiel…
Statistical exchange-coupling errors and the practicality of scalable silicon donor qubits
Yang Song, S. Das Sarma
Recent experimental efforts have led to considerable interest in donor-based localized electron spins in Si as viable qubits for a scalable silicon quantum computer. With the use o…
Impurity-driven intervalley spin-flip scattering-induced 2D spin relaxation in silicon
Yang Song, S. Das Sarma
Through the theoretical study of electron spin lifetime in the 2DEG of doped Si, we highlight a dominant spin relaxation mechanism induced by the impurity central-cell potential ne…
Spin relaxation of hot electrons in the Gamma-valley of zinc-blende semiconductors
Yang Song, Hanan Dery
We present a technique to calculate the spin relaxation of hot electrons during their energy thermalization in the Gamma-valley of zinc-blende semiconductors. The results of this m…
