Abstract: Optimal routing in quantum-repeater networks requires finding the best path that connects a pair of end nodes. Most previous work on routing in quantum networks assumes utility functions that are isotonic, meaning that the ordering of two paths does not change when extending both with the same edge. However, we show that utility functions […]

Abstract: Hole spin qubits in silicon nanostructures offer fast, all-electrical control through electric-dipole spin resonance (EDSR), yet their performance strongly depends on device geometry. In this work, optimization criteria of Rabi frequency of single-hole spin qubits in silicon-on-insulator (SOI) quantum dots are identified by combining electrostatic and kk⋅pp simulations with a perturbative model of the […]
