PROGRAM DEVELOPMENT SUPPORT DEVICE FOR COMPUTER SYSTEM INCLUDING QUANTUM COMPUTER, PROGRAM DEVELOPMENT SUPPORT PROGRAM, AND SIMULATION DEVICE

摘要

A section detector 12 detects a section in a source code written in the C++ language for performing a database search process, and a processing time estimator 13 estimates both the processing time for the section by a conventional logic operation and the processing time by quantum computing based on Grover's search algorithm. If it is determined that the latter is shorter than the former by a determiner 14, a replacing processor 15 replaces the section with a program written in C++ corresponding to Grover's search algorithm. Accordingly, a source code is completed in which a portion or portions suitable for computing by quantum computer is replaced. Thus, with the present invention, it is possible to easily develop a program for simulating a cooperative operation between a quantum computer and a conventional computer in a computer system including the two types of computers.
