Parameter: If a method needs to receive arguments, then the method call should pass some parameters. The parameter variable is assigned with the value of an argument when the method is called. Reference parameter: Reference parameter is one of the special parameter variable types that are used for two-way communication purposes. If an argument is passed to a reference parameter, it will not get the copy of the argument value. Instead, it acts as a reference for the argument passed to it. If any change or modifications is done to the reference parameter, then that change will be reflected to the argument it references.

Question

Chapter 6.4, Problem 6.13CP

Program Plan Intro

Parameter:

If a method needs to receive arguments, then the method call should pass some parameters.

The parameter variable is assigned with the value of an argument when the method is called.

Reference parameter:

Reference parameter is one of the special parameter variable types that are used for two-way communication purposes.

If an argument is passed to a reference parameter, it will not get the copy of the argument value. Instead, it acts as a reference for the argument passed to it.

If any change or modifications is done to the reference parameter, then that change will be reflected to the argument it references.

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…
