What is the difference between ideal and noisy simulation?

Question: What is the main difference between ideal and noisy quantum simulation? A) Ideal simulation ignores physical noise, while noisy simulation models errors such as gate noise or measurement noise B) Noisy simulation does not use qubits C) Ideal simulation always runs on real hardware D) Noisy simulation prevents measurement Correct: A Explanation: Ideal simulation assumes perfect gates and measurements. Noisy simulation attempts to include realistic imperfections such as decoherence, gate errors, and readout errors. Topic: quantum computing / noisy simulation
