The objective of this article is to use a real quantum computer, for this we will use python and the Qiskit library provided by IBM which allows for simulating quantum computers. With only a few dozen lines of programming we can obtain the graphic display of our circuit that we…

The general structure of a quantum circuit is mainly made up of the juxtaposition of several quantum gates. Each gate acting on one or more qubits, as shown below As input, we have several qubits q1,q2,…,q_n that we call the quantum register. The superposition of these n qubits forms what…

In classical computing, when we combine two bits, we obtain four possibilities 00, 01,10, or 11. In a 2-qubit quantum computing, this corresponds to the superposition of four fundamental states, written as Where |0.0>,|0.1>,|1.0> and |1.1> are the four basic states which correspond to the vectors,

A quantum computer produces qubits that undergo transformations in a quantum circuit. These transformations are carried out by quantum gates that we will study in this article starting with the simplest quantum gates on the 1 qubit. We start with the X gate also called the NOT gate and which…

In this chapter, we will state the basic notions of quantum computing and they will be covered in detail in the following chapters. In classical computing, the basic unit of information is the bit, which is either 0 or 1. In quantum computing, it is different, we have 2 basic…

In this article, we will look at the different layers or infrastructure layers of a blockchain and understand the difference between layers 0,1, 2, and 3. To understand the interest of Layers, we come back to the Trilemma of the blockchain which states that an optimal blockchain must combine three…

In recent years we have had the emergence of several Layers 1 or infrastructure blockchains projects that use different types of structures to develop decentralized applications, smart contracts, and make transactions. …

The automotive industry is based on a whole creative process, which when it makes an innovation it is always small hazards that lead the world to unexpected places, whether it is a pure and simple innovation or just the improvement of an old technique. A slow and random process of…

Tornado cash was recently added to the Office of Foreign Assets Control (OFAC) list. In this article we’re going to explain what tornado cash and what the implications of it being added to the U.S sanctions list The objective of the Tornado cache is simply to anonymize certain addresses on…
