قدمنا في هذا العمل نموذجاً نظرياً لدراسة اهتزازات جملة كمومية بسويتي طاقة مفترضين وجود تفاعل متبادل بينهما من خلال: أولاً: تمثيل الجملة الكمومية ذات سويتي الطاقة بحفرتي كمون كموميتين لانهائيتين متآثرتين على بعد واحد x و متناظرتين بالنسبة لمبدأ الإحداثيات o، ثمّ إيجاد المتجهات الخاصة و القيم الخاصة لهما باستخدام معادلة شرودنغر المستقرّة Stationary Schrödinger’s equation. ثانياً: إثبات أنّ التقريب غير الاضطرابي كاف لكتابة مؤثر الهاملتوني لهذه الجملة، و لاشتقاق معادلة رابي للجملة Rabi’s equation، و تطبيقها مباشرة على مؤثر التطور للحالة الابتدائية للجملة.
We present a theoretical model for studying the oscillations among two-level quantum system when an interaction term is considered: First, we present the two-level quantum system with a symmetric double square potential well in interaction, in one dimension x, then we find the eigenvectors and the eigenvalues for this system by solving the stationary Schrödinger’s equation. Second, we proved that a non perturbative approach can be conveniently used to write the Hamiltonian operator and to derive the Rabi’s equation for this system, directly applying the time evolution operator to the initial state of the system.

Quantum Computers can be considered the biggest threat against cryptography algorithms especially the public key algorithms. In this seminar, we will discuss Quantum Computers starting from a simple explanation about the physics and mathematics basic
s behind these computers, then explaining why these computers are special in regard of cracking the public key algorithms. Finally, we will describe an example of quantum resistant algorithms.
Recent research has investigated quantum NLP, designing algorithms that process natural language in quantum computers, and also quantum-inspired algorithms that improve NLP performance on classical computers. In this survey, we review representative
methods at the intersection of NLP and quantum physics in the past ten years, categorizing them according to the use of quantum theory, the linguistic targets that are modeled, and the downstream application. The literature review ends with a discussion on the key factors to the success that has been achieved by existing work, as well as challenges ahead, with the goal of better understanding the promises and further directions.
This research deals with metaphysics as an essential structure in any
scientific work. This has been achieved through intuitional analysis of
facts as well as mathematics and presumptions that are based on the
“core”, let alone the teleological or
ientation in science and the
contradiction between appearance and reality.
The paper finds out that the metaphysical structure in science is
formed in accordance with the formational structure of the human mind,
and it provides various items of evidence to prove this.
This research do the Feasibility important technical of EOR
(Enhanced Oil Recovery ) techniques (Chemical Methods ) as
(Polymers, Surfactants, Alkaline ) in Syrian fields (Al Gbiseh/Case
Study/ ) , because of its high benefits in worldwide.
The Lee code is applied to characterize the plasma focus in two
plasma focus devices UNU/ICTP PFF and Amirkabir plasma focus
device (APF),
and for optimizing the nitrogen soft x-ray yields based on bank,
tubes and operating parameters. It is foun
d that the soft x-ray yield
increases with changing pressure until it reaches the maximum
value for each plasma focus device, with keeping the bank
parameters, operational voltage unchanged but systematically
changing other parameters.
