“…The strong 3D confinement in quantum dots also results in spin states that are, at least theoretically, expected to be more robust against decoherence compared to bulk materials [11,236,237]. This makes self-assembled QDs potential candidates for various spintronic applications and also for use in quantum information processing, where a spin confined to the QD can serve as a quantum bit.…”

“…While most research and applications in spintronics concentrates on extended structures, all spintronic effects can be reproduced with the systems involving few quantum states, for instance, realized in semiconducting quantum dots 16,17 . Spin filtering and detection have been demonstrated [17][18][19] and more research is underway 20 .…”

We investigate transport in a superconducting nanostructure housing a Weyl point in the spectrum of Andreev bound states. A minimum magnet state is realized in the vicinity of the point. One or more normal-metal leads are tunnel-coupled to the nanostructure. We have shown that this minimum magnetic setup is suitable for realization of all common goals of spintronics: detection of a magnetic state, conversion of electric currents into spin currents, potentially reaching the absolute limit of one spin per charge transferred, detection of spin accumulation in the leads. The peculiarity and possible advantage of the setup is the ability to switch between magnetic and non-magnetic state by tiny changes of the control parameters: superconducting phase differences. We employ this property to demonstrate the feasibility of less common spintronic effects: spin on demand and alternative spin current.
