Explanation of Solution

Importance of von Neumann bottleneck:

As we know that modern computers run on von Neumann architecture. Von Neumann Architecture uses a single memory to store data as well as programs and a processor to perform computations. Data and instructions flow from the memory to processor for computation and later the result is transferred back to the memory. But the problem here is that there is a single bus for transfer for instructions and data to the processor.

This greatly reduces the throughput of the processor as the processor has to remain idle for most of its time waiting for the data from the memory. This problem is popularly known as von Neumann bottleneck. Even though in recent years there has been significant increase in the processor speed, but it just means that the processor will remain idle for more time. There have been improvements in the memory density...

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…
