WebJul 20, 2024 · Grover’s algorithm starts by preparing an equal superposition of N states corresponding to all the N items of the list. The Grover’s iterate is then applied on this superposition, \sqrt {N} number of times. The final state is then measured; it is known that the observed state represents the item of interest with high probability. WebThe composition of these two rotations forms a Grover iterate, which needs to be applied only O(p1 p) times in order to obtain a high probability of measuring jsuccession the third register. The rotations that make up the Grover iterate can be …
