Numerical simulations predict that tensile or unstrained germanium heterostructures yield spin splittings over 100 times larger than compressive cases, enabling GHz Andreev spin qubits with 100 ns all-electric gates.
Gate-based RF reflectometry on large-area SiC transistors shows gate-dependent response that degrades at cryogenic temperatures due to carrier freeze-out in the drift region, with a proposed modified circuit to restore sensitivity.
