Explanation of Solution

Relational Diagram:

  • A relational diagram refers to a visual representation of the relational database’s entities, the relationships between those entities, and the attributes within those entities.
  • Therefore, it makes it easy to understand what the entities represent, what types of relationships exist and how these relationships are implemented.

Example of Relational Diagram:

  • The relational diagram given below shows the connecting fields that is, “AGENT_CODE” through 1:M relationship type.
  • To illustrate simple relational diagrams, use MS Access, Database tools, and “relationships” options on the main Access menu...

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…
