摘　　要：In this work, we demonstrated a fixed-point quantum search algorithm in the nuclear magnetic resonance (NMR) system. We constructed the pulse sequences for the pivotal operations in the quantum search protocol. The experimental results agree well with the theoretical predictions. The generalization of the scheme to the arbitrary number of qubits has also been given.In this work, we demonstrated a fixed-point quantum search algorithm in the nuclear magnetic resonance （NMR） system.
