Grover algorithm for a list of 8 elements
WebJan 5, 2024 · Devised by Lov Grover in 1996, Grover’s Algorithm provides an incredible speedup from its classical counterpart. It’s a searching algorithm that allows us to find a certain element in its respective list in O(√N) time, rather than O(N) time and thus, the quadratic speedup. WebLet's assume an N = 8 element database that contains colors Red, Orange, Yellow, Green, Cyan, Blue, Indigo and Violet, and not necessarily in this order. My goal is to find Red in the database. The input for Grover's algorithm is n = log 2 ( N = 8) = 3 qubits, where the 3 qubits encode the indices of the dataset.

The initial state can be interpeted, in the context of cognitive processes, as a guessing state, representing the initial mental weights relevant to the items. If a > t/N , this means that the good items have initially more relevance than the bad items.
