Result Therefore, all inductors are represented by only one quantum register. Thus, the entire set is represented by one chromosome in superposition, and it is written as follows: α 1 α 2 ......α j β 1 β 2 .........β j i = c 0 |00.....00 > +c 1 |00...01 > +c 2 n −2 |11...01 > +c 2 n −1 |11...11 > (2) One of the main stages of the AQGA is the relationship between the single quantum register |x> i and the objective | finness x > i function of the quantum register |ψ> i = |x> i ⊗ | fitness x > i (3) From a formal point of view, we have a quantum gate F that evaluates the real state of people (Figure 1). In 2008, a similar idea have been used in another version of a real quantum evolution algorithm called the Quantum Genetic Optimization Algorithm (QGOA). FIGURE 1. Fitness quantum door. At the second stage, the algorithm searches for maximum compatibility: | fitness x > i max (4) In the late of 1990s [8], a quantum algorithm was proposed to find the maximum value between the values of N. After applying of F operator, the reduced quantum genetic algorithm searches for the maximum value of the objective function based on the Grover search algorithm [9]. It is one of the most popular quantum algorithms for searching a chaotic database. The abbreviated quantum genetic algorithm performs the following two steps. Firstly, Oracle O has been created to define all sets in a register that has a set of objective function values: |ψ> i Desired value that exceeds the maximum value, o |ψ> Q (t) = (−1) f (x) |ψ> Q (t) (5) 030002-3 here f (x) = 1 ,i f | fitness x > i = | fitness x > i max 0 ,otherwise (6) Secondly, the algorithm is completed using the Grover diffusion operator. This operator is used to find specified states, i.e. f (| fitnes x > i ) = 1: |ψ> Q (t) = G|ψ> Q (t) (7) Finally, the maximum number of chromosomes is obtained by performing ψ> Q (t) . All of these steps are summarized in the quantum system shown in Figure 2. FIGURE 2. Fitness quantum door. CONCLUSION In conclusion, it is important to say that, in this article, we have examined the basic concepts of quantum computing and quantum evolution. In recent years, the ability to simulate a quantum computer has led to the emergence of new genetic algorithms, namely quantum genetic algorithms. Currently, research in this class of algorithms is divided into two trends. On the one hand, this allows some researchers to create a new class of genetic algorithms in quantum mechanics. In this case, the researcher has no plans to run the algorithm on a quantum computer in the near future. The principal goal is to solve an optimization problem in a digital computer, or to test hardware technologies in a quantum genetic algorithm, or to solve real problems using a new class of algorithms instead of classical genetic algorithms. Given the way we think through these algorithms, we believe this latest research could have a profound impact on artificial intelligence and artificial life, as well as sciences like biology.
