Abstract.

In article some basic concepts and ideas of quantum computer science are considered. Much attention is paid to key properties of quantum systems – the quantum superposition and a quantum entanglement, which allows to realize the advantage of quantum parallel computing and quantum networks. The communications protocol of quantum teleportation is explained. Some results of creation of quantum networks and quantum computers are discussed.

Keywords:

quantum computing, qubit, quantum superposition, quantum entanglement.

PP. 34-44.
