Chapter 12, Problem 12E

a.

Program Plan Intro

Given:

File size = 2048 bytes

Payload size = 512 bytes

Given that systems are running in IPv4.

We know that:

Size of TCP header = 20 bytes

Size of IP header = 20 bytes

Total size = 40 bytes overhead per segment

The file size can be divided into 4 segments each segment contains 512 bytes. So, there are (40 + 512) × 4 = 2208 bytes in total.

So totally 2208 bytes will be sent by 4 segments.

b.

Program Plan Intro

Given:

File size = 2048 bytes

Payload size = 512 bytes

Given that systems are running in IPv6.

We know that:

Size of TCP header = 20 bytes

Fixed length of IPv6 = 40 bytes

Total size = 60 bytes overhead per segment

The file size can be divided into 4 segments each segment contains 512 bytes. So, there are (60 + 512) × 4 = 2288 bytes in total.

So totally 2288 bytes will be sent by 4 segments.

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…
