Chapter 4, Problem 17RQ

Explanation of Solution

Pairwise disjointness test:

Pairwise disjointness test: It is the test used to check whether there is a Left recursion exist in a grammar or not. If a grammar passes this test, it means it is non-left recursive grammar.

Concept of left recursion:

AAa|b

Example of a left recursive grammar:

Means if first symbol on RHS is same as LHS, then the following grammar is known as left recursive

I need help to solve a simple problem using Grover’s algorithm, where the solution is not necessarily known beforehand. The problem is a 2×2 binary sudoku with two rules: • No column may contain the same value twice. • No row may contain the same value twice.   Each square in the sudoku is assigned to a variable as follows:   We want to design a quantum circuit that outputs a valid solution to this sudoku. While using Grover’s algorithm for this task is not necessarily practical, the goal is to demonstrate how classical decision problems can be converted into oracles for Grover’s algorithm.   Turning the Problem into a Circuit   To solve this, an oracle needs to be created that helps identify valid solutions. The first step is to construct a classical function within a quantum circuit that checks whether a given state satisfies the sudoku rules.   Since we need to check both columns and rows, there are four conditions to verify: v0 ≠ v1   # Check top row   v2 ≠ v3   # Check bottom row…
