(author), Samkharadze, Nodar (author), Sammak, A. (author), Vandersypen, L.M.K. (author), Scappucci, G. (author) Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction band valleys, which compete with the spin degree of freedom in the formation of qubits. Despite attempts to enhance the valley energy splitting deterministically, by engineering a sharp interface, valley splitting fluctuations remain a serious problem for qubit...
