Precision Measurement of the Beam-Normal Single-Spin Asymmetry in Forward-Angle Elastic Electron-Proton Scattering

Kavli Affiliate: A. C. Davis | Summary:A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the two-photon exchange process. We report a 2% precision measurement of the beam-normal single-spin asymmetry in elastic electron-proton scattering with a mean scattering angle of […]

Ultrafast coherent control of a hole spin qubit in a germanium quantum dot

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Gang Xu, Fei Gao, He Liu, Rong-Long Ma | Summary: Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in germanium (Ge) intriguing candidates for spin qubits with […]
