N.K. Uvarov, А. Д. Хомоненко
Abstract
Modern variants of Grover›s algorithm and approaches to their implementation are considered. The definition of Grover›s algorithm given, its main three stages are indicated. A generalization of Grover›s algorithm «amplitude amplification» is given. A description of the quantum circuit of Grover›s algorithm is given. An example of a complete Grover quantum circuit for two qubits is considered. The characteristic of quantum search in d-dimensional system with the help of qutrits and qudits is given. Examples of implementation of a number of variants of Grover›s algorithm using IBM Quantum Composer tools are proposed. Descriptions of the latest modifications of Grover›s algorithm are given.
