Amplitude Amplification
Fundamental quantum technique used by Grover's algorithm to iteratively increase the measurement probability of quantum states corresponding to the sought solution.
Quantum Oracle
Black-box quantum function that marks solution states by inverting their phase, serving as a search criterion in Grover's algorithm without revealing the internal structure of the problem.
