The aim of this tutorial is to explain in simple words and simulate practical quantum problems on real quantum machines. Well, I'm also a beginner in this area and I want to learn during the tutorial creation. Hopefully, after the tutorial you and me will have better understanding over quantum world and it's application in real world.

## Requirements:

• basic understanding of math
• web browser
• basic knowledge or programming

In case that you don't have math or programming background you will be able to follow the course a slower pace. But with high motivation and time devoted to this area you will be able to outperform the average people.

## Introduction and resources

First you may want to read this two articles for quantum computing:

Have in mind that this Quantum Computing (QC) is still developing. This is a list of useful resources that I found for myself:

Interesting videos on the topic:

## Basics for beginners

This technology is relatively new and just starting to develop in new areas other than physics. The term is born in science around 1900 and made a significant change in our understanding of the world and universe. Some of the explanations are beyond our understanding.

#### Qubit and superposition for beginners

Imaging rolling a dice or tossing a coin. During the roll or the toss you don't know what will be the final result. For a coin you have two states:

• tail

With probability 50% for each. We can mark them with 1 - head and 0 - tail. And this is the classic representation for a bit. The working language of classical computers. For a bit you have only two states - 0 and 1.

Moving to quantum computer and respectively the qbit or quantum bit you have one more state or so called superposition. Which can be explained as having the 0 and 1 at the same time. The coin to be tail and head simultaneously.

You can imagine this as the time when the coin is in the air and you have repeating tails to heads. The same is when you roll a dice - it's getting different positions and out numbers. Of course at the end when you measure the final state you know exactly what is the result.

So the simplest imagination would be something like:
