Explanation of Solution

Solutions formed altogether in a four queens problem

  • The four queens problem is to determine when the two queens attack each other diagonally.
  • There are four partial solutions with a queen in row 1 in a blank board.
  • When the queen is in column 1, there are four partial solutions with a queen in row 2.
  • Then two of them will be abandoned immediately.
  • The other two lead to partial solutions with three queens but one of the three queens will be abandoned...

.NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…
