Abstract
If we have to search an unsorted database or solve an unstructured search problem, we can use a quantum search algorithm [1] . As of now, a quantum search algorithm like Grover’s algorithm [2] takes Ω ( N ) time, where N is the size of the search space. This paper proposes an improved quantum search algorithm that yields the correct result in constant time with a high probability.
