What makes a cluster state a computational resource?

Question: Which statement best describes the role of a cluster state in measurement-based quantum computation? A) It is merely a classical lookup table for measurement angles B) It is an entangled resource state consumed by local measurements that implement logical gates C) It is a product state whose qubits become entangled only after all measurements are finished D) It is equivalent to storing the complete output distribution before the computation begins Correct: B Explanation: MBQC begins with a highly entangled resource state. Computation proceeds by measuring qubits in chosen bases, consuming the entanglement and propagating logical information through the measurement pattern.
