Abstract
The problem of control of quantum dynamics particle has been studied. The general equations have obtained for a description of this problem. The criteria for optimal time, reaching the desired point, have been obtained and have analyzed. The different types of spectrum of acting fields using for control, from impulse form of the field to the power form and Gauss distribution force spectrums, have been studied.
Highlights
A lot of works on search of materials for development of qubits as bases of element base for quantum calculations has conducted. It is conducted in several directions, but the most perspective, in our opinion, possibility of creation of qubits on the basis of low-dimensional quantum semiconductor systems with quantum dots is represented [1]
With search of perspective materials, the important problem is development both the new and other adapted under concrete quantum nanostructures algorithms and schemes of the quantum calculations allowing to realize logical schemes and elements
80 Research Advances in Quantum Dynamics mation for polynomial number of operations depending on the task size
Summary
A lot of works on search of materials for development of qubits as bases of element base for quantum calculations has conducted. The first class of algorithms is intended for the solution of tasks like factorization of numbers, the second class of algorithms is developed for modeling of the quantum phenomena [9], and the third class of algorithms is intended for search of object in an unstructured random database [10]. In this first part of the chapter, the possibility of control of spin states in quantum dots as bases of creation of logical elements on the basis of quantum semiconductor systems has discussed. The second type of states is important for storage of the information
