摘　　要：We study the entanglement properties of the superposed state of orthogonal maximally entangled states. It is shown that the superposed state is maximally entangled and the superposed state is separable. The relation between the superposed state and the mutually unbiased state is discussed.We study the entanglement properties of the superposed state of orthogonal maximally entangled states.
