Research and Development Circuits for Error Correction

One of the main problems to be overcome in the near future for the practical creation of quantum computer to make quantum computing resistant to interaction with the external environment and to eliminate inaccuracy of operations. In this paper we study quantum codes correcting errors, proposed as a way to protect against the occurrence errors due to the influence of the external environment. Results of work are considered software implemented model of the simplest quantum code. A number of questions related to quantum computing are also raised. In their works, Shor (factorization algorithm), Grover (search in a disordered database) and a number of other scientists showed that a quantum computer (QC) is capable of processing a small class of functions with higher performance than any of the existing “classic” computers. This work is a study of the influence of the environment on the quantum system of qubits. The article is supposed to describe the foundations of quantum information theory, as well as the place in it of the concept of quantum entanglement. A technique for correcting two main types of quantum errors has been developed, based on the implementation and execution of certain quantum circuits. The main difficulties of ensuring the protection of a quantum channel from various types of errors are analyzed and considered.
