摘      要：正We present an experimental study of controlled-NOT（CNOT）gate through four-wave mixing（FWM）process in a Rubidium vapor cell.A degenerate FWM process in a two level atomic system is directly excited by a single diode laser,where backward pump beam and probe beam are Laguerre Gaussian *** means of photons carrying
