The applicability to quantum operations, however, depends on the viability of macroscopic quantum tunneling, a precondition for a quantum computer. I will discuss how by tuning the external fields, magnetic skyrmions in frustrated magnets offer a platform for the observation of diverse quantum tunneling effects [2], We predict quantum tunneling processes for a typical skyrmion spin texture of a 5 nm radius to occur with an inverse escape rate within seconds below 100 mK. In the absence of an energy bias, quantum tunneling effects give rise to an energy tunnel splitting in the MHz regime. Our studies suggest that quantum mechanics manifests itself at the macroscopic level of skyrmion helicity. We offer the parameter space for a practical recipe in device architectures to explore magnetic helicity in the solid-state for qubit operations.
