  A distributed computing approach to solve the curse of dimensionality, caused
by the complex quantum system modeling, is discussed. With the help of Cannon's
algorithm, the distributed computing transformation of numerical method for
simulating quantum unitary evolution is achieved. Based on the Tavis-Cummings
model, a large number of atoms are added into the optical cavity to obtain a
high-dimensional quantum closed system, implemented on the supercomputer
platform. The comparison of time cost and speedup of different distributed
computing strategies is discussed.
