<P>PROBLEM TO BE SOLVED: To reflect an error generated in a quantum computer using an actual physical system on an arithmetic operation for quickly executing the arithmetic operation equivalent to that of the quantum computer. <P>SOLUTION: The conditions of logical values which can be expressed with N bits are shown with probability information, and a normal arithmetic operation corresponding to a quantum algorithm based on an instruction from the outside and an arithmetic operation equivalent to an error arbitrarily inserted between the normal arithmetic operations according to the instruction of an error generating part 4 are executed in parallel concerning the conditions of the different logical values by using the probability information. Thus, it is possible to quickly obtain the arithmetic result including the influence of the pseudo generated error, and to quickly execute the arithmetic operation by reflecting the error on the arithmetic operation corresponding to the quantum algorithm. <P>COPYRIGHT: (C)2004,JPO |
