Grover’s Algorithm: Fast Quantum Search Algorithm - Medium

WebJul 18, 2024 · Grover’s Algorithm was developed by Lov Grover as a quantum search algorithm designed to only need O(√N) O ( N) runtime in contrast to classical search algorithm’s which require O(N) O ( N). The idea behind Grover’s algorithm is to first use an oracle to mark the correct answer by applying a negative to the correct answer. WebDec 27, 2024 · We show that an optimal and exact quantum amplitude-amplification algorithm corresponds to the Grover algorithm together with a single iteration of QAAO. We then realize three-qubit QAAOs with current quantum technologies via cloud-based quantum computing services, IBMQ and IonQ. high air forces 1
