The paper develops a Simple Quantum Inspired Evolutionary Algorithm and evaluates it on some classical numerical optimization problems and the Need-in-a-haystack problem.The proposed algorithm represents a qubit with a radian and uses only one quantum chromosome.Special operators of rotation and mutation and the method to evaluate a quantum chromosome are presented too.Compared with some other quantum inspired genetic algorithms and the classical genetic algorithm

the novel algorithm shows the outstanding performance and solves the Need-in-a-haystack problem perfectly.
