We address attention to the 3D lattice match between hexagonal lonsdaleite, a carbon allotrop denser and harder than diamond with a higher carrier mobility, and tetragonal stishovite (rutile structure). Both compounds are obtainable via shock wave synthesis route. Stishovite seeding may lower the high-pressure and low temperature synthesis conditions for lonsdaleite as a coming material for quantum computer chips better withstanding solar wind damage. The chips could be made of a forest of lonsdaleite nanorods with defect center based addressable high-fidelity and non-destructive qubits. Material science as well as geochemistry may gain profite from the remarkable three-dimensional lattice coincidence between stishovite and lonsdaleite as a groundbreaking suggestion. Interestingly, carbon dioxide can adopt the rutile structure at extreme conditions of pressure and temperature. This paws the way for new oxygen defect based research on lonsdaleite as chip material.
