Spin-orbit splittings in Si/SiGe quantum wells
M. Prada, G. Klimeck, R. Joynt
We present a calculation of the wavevector-dependent subband level splitting from spin-orbit coupling in Si/SiGe quantum wells. We first use the effective-mass approach, where the…
Spectroscopy of Valley Splitting in a Silicon/Silicon-Germanium Two-Dimensional Electron Gas
Srijit Goswami, Mark Friesen, J. L. Truitt +8
The lifting of the two-fold degeneracy of the conduction valleys in a strained silicon quantum well is critical for spin quantum computing. Here, we obtain an accurate measurement…
Rashba spin-orbit coupling and spin relaxation in silicon quantum wells
Charles Tahan, Robert Joynt
Silicon is a leading candidate material for spin-based devices, and two-dimensional electron gases (2DEGs) formed in silicon heterostructures have been proposed for both spin trans…
Pseudo-Digital Qubits: A General Approach
Mark Friesen, Robert Joynt, M. A. Eriksson
Pseudo-digital coupling has recently been proposed as a simple but robust technique for reducing gating errors in quantum dot quantum computers. Here, we discuss the technique in t…
