We hear more and more about the quantum computer in the media, but without really understanding what it is.
Do not worry, it's not your fault: quantum computing is a bit complex at first glance. But thanks to this article, you will discover:
Why do we really need quantum computers?
... and why they are a bit scared anyway.
How do quantum algorithms work?
Basic notions in physics to understand how they work;
And the answers to big questions like: are we all going to have our quantum computer in the living room?
Before you begin, you must be sure to understand the basic operation of a normal computer.

What is it, a quantum computer?
Even if we have the impression that a computer does a lot of things, in reality, it has only one mission: it deals with information (hence the word "computer").
Your computer stores information on your hard drive processes information with its processor (such as the page you're reading or a movie you're watching), and turns that information into sound (in your speakers) or in the picture (on your screen). Period.
This information manipulated by the computer has the characteristic of being coded in binary, that is to say with 0's and 1's. In other words, a computer reflects in binary. A computer memory is thus made up of billions of boxes containing either a 0 or a 1. Such a box is called a bit. To manipulate these bits, your computer is filled with small electronic components that work together and that are called "logic gates".
The code of any program, encoded in binary, to be usable by a computer
Your computer can not solve all your problems!
There is also the impression that computers can solve all the problems of the world because they are powerful and effective. And that's wrong!
Researchers often encounter problems that their computers can not solve. So, they are looking for ways to make their computers more powerful. To make a computer more powerful, you have to:
increase its memory (to store + information).
increase the number of transistors it has (to process more information).
Unfortunately, there comes a time when adding memory and processor is not even enough to make the computer satisfactory.
