WebShor’s algorithm¶. Let us now show that a quantum computer can efficiently simulate the period-finding machine. As in the case of the Deutsch-Jozsa algorithm, we shall exploit quantum parallelism and constructive interference to determine whether a complicated function has a certain global property that cannot be learned by evaluating the function … Suppose there are N=2nN=2n eligible items for the search task and they are index by assigning each item an integer from 00 to N−1N−1. Further, suppose that there are MM different valid inputs, meaning that there are MM inputs for which f(x)=1f(x)=1. The steps of the algorithm are then as follows: 1. Start with a … See more Any search task can be expressed with an abstract function f(x)f(x) that accepts search items xx. If the item xx is a solution to the search task, then f(x)=1f(x)=1. If the item xx isn't a solution, then f(x)=0f(x)=0. The search problem … See more To illustrate the process, let's follow the mathematical transformations of the state of the register for a simple case in which there are only two qubits and the valid element is 01⟩. 01⟩. … See more As the probability of success can be written as a function of the number of iterations, the optimal number of iterations NoptimalNoptimalcan be found by computing the smallest positive integer that (approximately) … See more To see why Grover's algorithm works, let's study the algorithm from a geometrical perspective.
