Why are magic states important?

Question: Why are magic states important in fault-tolerant quantum computing? A) They are classical random bits B) They remove the need for logical qubits C) They measure all qubits without collapse D) They provide a way to implement non-Clifford operations fault-tolerantly Correct: D Explanation: Fault-tolerant architectures often handle Clifford operations more naturally than non-Clifford operations. Magic states enable the injection or distillation of non-Clifford resources such as T gates. Topic: quantum computing / magic states / fault tolerance
