What is amplitude amplification?

Question: What is the goal of amplitude amplification? A) Increase the probability of measuring desired solution states B) Increase the number of physical qubits automatically C) Remove all quantum gates from a circuit D) Make measurement reversible Correct: A Explanation: Amplitude amplification increases the probability amplitude of desired states while reducing the probability of undesired states. Grover's algorithm is the most famous example. Topic: quantum computing / amplitude amplification
