The purpose of this study was to present a competence model for leaders of quantum organizations. This research was exploratory and mix method (qualitative and quantitative). In the qualitative part of the statistical society, the research was conducted by professors of management from different universities and the statistical population of the quantitative part of the research consisted of the managers of the companies affiliated to the oil industry in Isfahan. The sampling was carried out in a multistage targeted manner based on classification method Fits the volume. The data gathering tool consisted of two researcher-made questionnaires. Their formal and content validity was confirmed by professors in management in the field of quantum organization and competence of the leaders. Reliability of the questionnaires was calculated by calculating the Cronbach's alpha coefficient, all of which were above 0. 70 and were desirable. The competency model of the quantum organization leaders was presented using structural equation modeling technique with 5 competence dimensions: individual, interpersonal, managerial, analytical / perceptual, technical, and 57 competencies of leadership.

The traditional management skills of planning, organizing, directing and controlling are insufficient in the fast-pacing, constantly changing, and highly complex world of twenty-first- century organizations. The quantum age is upon us and no part of human life is unaffected by this change and its new realities. Its impact on management and leadership is just beginning to be defined. If leaders and their organizations are to thrive in the new era, a whole new mind-set and skill-set must emerge in managers. While a fall in the number of nursing leaders may be attributed to the current nursing shortage, studies have noted that there is also a significant deficiency in their number. We need nursing leaders to exert that influence and by nurturing both leadership as well as clinical skills, we can do it. In contrast, at the bedside, they rarely find the opportunity to apply even basic leadership principles.Based on quantum approach to management, managers need to have a new perspective to man, processes and things. Also, this model considers the connection between things, man and elements much more important than the parts themselves. New challenges in leadership are avoiding centralization, maintaining flexibility, repeated designing and establishing structure to support culture and goals of followers. The new definition of system, therefore, is a set of rotary processes moving between order and chaos according to required needs. In quantum model for efficiency of leadership, seven skills, seven traits and seven principles are referred. This paper explains effective factors in quantum leadership and quantum organization.

Quantum computing is a new method of information processing that is based on the concepts of quantum mechanics and leads to strange and powerful events in the quantum field. The logic synthesis of quantum circuits refers to the process of converting a given quantum gate into a set of gates that can be implemented in quantum technologies. The most famous logic synthesis methods are CSD and QSD. The main goal of this study is to present a multi-objective logical synthesis method combining the above two methods in the quantum circuit model with the aim of optimizing the evaluation criteria. In this proposed method, the solution space is created from different combinations of CSD and QSD decomposition methods. The created solution space is a space with a very large exponential size. Then, using a bottom-up approach of multi-objective dynamic programming, a method is presented to search only a part of the entire solution space to find circuits with the optimal Pareto costs. The obtained results show that this method creates a balance between the evaluation criteria and produces many optimal Pareto solutions that can be selected according to different quantum technologies.

In this paper, we investigate quantum renormalization group theory in transverse Ising model on one dimensional chain of spin-1/2 particles. To this end, we employ recursion relations to quantum renormalization of coherence measure at ground state. Coherence measure diagram in terms of intensity of transverse field for higher renormalization steps shows the detection of quantum phase transition point for transverse Ising model which implies that the coherence measure can be a good indicator of quantum phase transition in transverse Ising model. Also, we obtain the divergence behavior that governs the first derivative of the coherence measure behavior, near to critical point. Although the coherence measure depends on the basis of writing the density matrix, results show that the quantum phase transition point detected by coherence measure is independent of selected basis.

The modification of laws of physics at short intervals is an important result of the theory of quantum gravity. For instance, commutative relations of standard quantum mechanics change on scales of length-called Planck length. It should be noted that these changes can be neglected at low energy levels but they are considerable only at high energy levels such as the initial universe. In this regard, the principle of uncertainty of standard quantum mechanics is changed with modified relations of uncertainty including a visible minimum of Planck order. Early moments of the universe, which included the inflation period, was a period with noticeable effects of quantum gravity due to the high energy level, and as such, the effects can be studied during this period. To do this, characteristics of the inflation period can be examined according to initial parameters of the universe such as the initial fluctuations in the formation of the universe structure and the spectral index. On the other hand, vector cosmology models have been taken into consideration by researchers. These models include an action in which a vector field (in addition to the scalar field) is included to investigate effects of violation of the Lorentz invariance in observations. The present paper investigated effects of quantum gravity (with effects on non-commutative geometry and generalization of the uncertainty principle) on parameters of a vector cosmological model. The vector model was used as this scenario had acceptable adaptation to parameters of cosmology after inflation (e. g. the transition from the Phantom boundary, etc. ) (Nozari and Sadatian, 2009). Furthermore, the present study could test this vector model for determining parameters of the inflation period based on effects of quantum gravity. According to calculations in the present paper, we concluded that, first: the density of scalar perturbations decreased in the vector model based on effects of quantum gravity (the reduction of standard model was more considerable), and second: due to the ignorance of effects quantum gravity, the scalar spectral index parameter remained invariant as observations indicate, but due to large enough gravitational effects (depending on amount of β), the spectral index parameter is not maintained its invariance scale. According to obtained modification in the present study, the quantum gravity can be tested for the density of scalar perturbation (which can be measured by observing the spectrum of cosmic microwave background radiation). In order to compare our results with other studies, we can refer to (Zhu et al, 2014) where they examined the spectral index in accordance with high-order correction mechanism. It also indicated that a single asymmetric approximation does not lead to a considerable error value for the spectral index, and the invariance scale is maintained. Furthermore, the paper (Hamber and Sunny Yu, 2019) found the same results for invariance scale of the spectral index according to the Wilson normalization analysis method. Therefore there was no need to have common assumptions in the inflation period. Finally, it should be noted that despite a great number of studies on effects of quantum gravity, the reviewed model of this paper considers a state in which the effects can be investigated at all stages of the universe evolution from inflation till now.

A fundamentally quantum model of computation based on quantum entanglement and quantum measurement is called one-way quantum computation model (1WQC). Computations are shown by measurement patterns (or simply patterns) in this model where an initial highly entangled state called a graph state is used to perform universal quantum computations. This graph together with the set of its input and output qubits is called the geometry of the pattern. Moreover, some optimization techniques have been introduced to simplify patterns.Previously, the 1WQC model has been applied to optimize quantum circuits. An approach for parallelizing quantum circuits has been proposed which takes a quantum circuit and then produces the corresponding pattern after performing the proposed optimization techniques for this model. Then it translates the optimized 1WQC patterns back to quantum circuits to parallelize the initial quantum circuit by using a set of rewriting rules.To improve previous works, in this paper, a new automatic approach is proposed to optimize patterns based on their geometries instead of using rewriting rules by applying optimization techniques simultaneously. Moreover, the optimized pattern is translated back to a quantum circuit and then this circuit is simplified by decreasing the number of auxiliary qubits. Results show that the quantum circuit cost metrics of the proposed approach is improved as compared to the previous ones.
