Cluster states, a specific class of multi-partite entangled states, are of particular importance for quantum science, as such systems are equivalent to the realization of one-way quantum computers. Here, we demonstrated the generation of d-level cluster states using a high-dimensional time-frequency-domain approach in combination with a deterministic controlled phase gate. We then implemented d-level measurement-based quantum computing operations and showed the state*s high tolerance towards noise.
