The implementation of error correction protocols is a central challenge in the development of practical quantum information technologies. Recently, multilevel quantum resources such as harmonic oscillators and qudits have attracted interest in this context because they offer the possibility of additional Hilbert space dimensions in a spatially compact way. Proposals employing nuclear spin qudits hyperfine-coupled to electron spin qubits demonstrate remarkably efficient encodings for protection against commonly encountered decoherence channels [1,2]. I will review the principles of
these proposals and present our progress in experimental implementations, using combined electron and nuclear spin resonance applied to a test system, the Mn defect in ZnO.
