Chapter 5, Problem 5.27RQ

Explanation of Solution

One-to-many relationship (1:N):

One-to-many relationship is one of the types of binary relationship that refer to the relationship between two entities which means one parent field or record can be associated with one or more child field or record.

ID-dependent entity:

In the entity-relationship model, an identifier of one entity is dependent on the identifier of another entity and it is special kind of weak entity.

  • In entity-relationship model, id-dependent entity is represented as rounded corners.
  • Note: Identifier is an attribute which is used to uniquely identify a particular entity instances from an entity.

Example:

In a class database, a teacher can teach many subjects, but the subject would not have same kind of relationship with the teacher.

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…
