The main purpose of cryptography is to hide data, this process is usually carried out by encrypting them. Over time, cryptography began to solve other problems similar to encryption in terms of methods of solving them, for example, the creation and distribution of tokens, the problem of audit of parties, etc. In this case, as a result of the coordinated efforts of users, the solution of such problems is called cryptographic protocols [1].
At the beginning of the XX century, it opened up a close connection between Informatics and physics. At first glance, success in solving many problems that are associated only with information technology and Information Protection can only be achieved in a physical way. Before the scientists, there were two main questions [2]: how large are the possibilities of quantum algorithms and how it is possible to create devices that implement these algorithms.
In the 60-ies of the XX century, when information technology and computer technology began to develop rapidly, a new science - quantum information theory was born. He studies quantum mechanical States and their ability to participate in the transmission and processing of data. Quantum theory is a mathematical model of modern understanding of the physical properties of the surrounding world and the physical systems that it consists of [3].
Basic concepts of quantum information theory. Quantum information theory works with quantum states, Studies their properties and laws. This science is built on the concepts of quantum states and wave function. On their basis, such concepts as quantum bit, the collapse of wave function and the Prohibition of cloning are formed.
