Query: Quantum implementation of elementary arithmetic operations   Quantum computation has received great attention in recent years for its
possible application to difficult problem in classical calculation. Despite the
experimental problems of implementing quantum devices, theoretical physicists
have tried to conceive some implementations for quantum algorithms. We present
here some explicit schemes for executing elementary arithmetic operations.
