A time-optimized method to control the unitary time evolution in a quantum unitary gate was proposed using the Heisenberg model.For two classes of states|00〉,|11〉and|01〉,|10〉,the time-optimized generation of any target entangled state under a uniform magnetic field was analyzed,and a novel strategy based on the time-optimized method to generate two qubit entangled states was suggested.The effectiveness of the proposed strategy was theoretically verified by simulations.
