From my discussion in ResearchGate social network on the relationship between electron spin and quantum computer states.
Magnetism offers quite a lot of possibilities to generated quantum states necessary for the creation and sustenance of computational operators. Electron Spin is largely a measurable quality. If you measure the minutest variations in the electron spin and a lot another magnetic properties, their ensemble will function as the ecosystem for computational operators with quantum capabilities. Thus material properties in the minutest level provides us excellent opportunities to create next generation computers. Next generation computers should offer maximum symmetry and similarity to the human nature ecosystem. This is the natural rode to the high performance and sustainable computational systems.
