Chapter 1, Problem 1.10RQ

Explanation of Solution

ID Column:

  • ID Column is a field which is used in databases having two or more themes and is divided according to the respective themes.
  • It is to provide uniqueness and avoid duplicity in the database and is quite similar to primary key but it differs from primary key as it is managed by the server and has the property of auto-incrementing which cannot be modified.

Example:

Cust_pet table:

...
sno Cust_fname Cust_lname Cust_phone Pet_type Pet_name
1 Green Robin 230-245-2546 Husky Shushi
2 Jackson Charles 213-235-2356 Malamute Leo
3 Pearson Jeffery 145-213-7658 Lebrador Rocky
4 Jackson

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…
