LinDCQ : uma linguagem para descrição de circuitos quânticos que possibilita o cálculo das operações na GPU utilizando JOCL

Abstract

This paper presents the LinDCQ tool — a description language and programming quantum circuits — which enables the creation of quantum circuits with calculus of operations performed in parallel on the GPU, using JOCL. The tool also allows the generation of graphically circuit. Used as a mechanism to generate grammars of languages and automata as language recognizer and the regular expression engine. In this context a discussion of the phases of compilers and on quantum computation is presented as well as an explanation of the main technologies used for the development of quantum circuits. LinDCQ The tool consists of: grammar in BNF form (Backus-Naur-Form), the compiler verifies that the incidence of errors in the code to be executed, a graphical interface to facilitate the programming features that allow the construction of the circuit graphically and parallel algorithms JOCL to perform operations that require greater computational cost in the GPU. At the end of an experiment is performed in order to assess the usability of the tool, to thereby ensure a higher level of user acceptance, facilitating interaction thereof with the tool developed in this work.
