Development Quantum Algorithms, Systems and Prevention or Elimination Quantum Types of Errors

The article proposes the structure of operators of quantum algorithms, its mathematical and schematic representation. The procedure for developing a quantum computing system or algorithm involves the presence of interference, quantum entanglement, and superposition. In a classical computer, the amount of data is measured in bits, and in a quantum computer, in qubits. A qubit is a quantum discharge or the smallest element for storing information in a quantum computer, as well as a quantum object that can be in a superposition of two states, that is, encode both a logical unit and zero at the same time. The general structure of the universal quantum algorithm is implemented as diagrams that reveal the basic elements, their properties, functions and place in the work of the quantum algorithm. The input value for the quantum algorithm is a binary function. A detailed decomposition of each block of the schematic diagram for the description of sequential processes and stages of quantum algorithms has been performed. A quantum block that runs n times is necessary for the sequential use of quantum operators and the subsequent measurement of the result of the entire computing process. Due to the probabilistic nature of quantum computing, the obtained basis vectors will contain some of the information necessary to solve a particular computational problem. Classical and quantum types of errors and methods for their elimination are described and developed. The main obstacles to protecting the channel from noise are the inability to copy data and information, the continuity of error and the destruction of quantum information during measurement (according to the principles of quantum computing, measuring a set of qubits without destroying the information encoded there is impossible). The bit and phase types of errors were corrected by modeling quantum circuits, three-qubit coding, and a set of quantum gates.
