qiskit-textbook Add Solutions for clarity of students reading the book

Is your feature request related to a problem? Please describe. Not a problem, an appendix with answers to the exercises would be helpful for everyone reading the book.

Describe the solution you'd like There are many questions left for the exercises. It would be helpful for the solutions for each unit.

Describe alternatives you've considered Not an alternative, simply an enhancement.

Additional context The solutions ribbon can be placed after each unit, like "Quantum States and Qubits", "Multiple Qubits and entanglement" etc.

Yes I will also like to see this change!

Here are my solutions to most of the quick exercises in sections 1 & 2. Before we can publish them:

The solutions need reviewing for accuracy.
Some questions also need reviewing (e.g. this question isn't great and should be changed / removed).

Hello frank, the solutions are pretty good. I have found small issues and suggestions and have noted them here:

Chapter: single qubit gates Quick Exercises 1 : Q4: Can represent in polar coords than bloch coords Quick Exercises 3: Q3: got this error “TypeError '>' not supported between instances of 'int' and 'NoneType'”(bloch_Mulivector for single qubit bug already issued)

Chapter: Phase Kickback Quick Exercises: Q2: CU1 should be by -pi/2 (did pi/2)

Also textbook bugs found:

Same Question number for all the questions in this exercise(Phase Kickback).
In chapter single qubit gates, on the right pane of contents, can’t move from one quick exercise to another by clicking.(QE1 and Quick Exercises 3 especially, minor bug)

+1 on providing solutions for the exercises. This would be beneficial to educators like myself who would like to use the Qiskit textbook in their courses.

I've uploaded my solutions to the exercises from chapters 1 and 2. Would love comments and/or suggestions, and hope I can contribute something directly to the textbook as well.
