主　　题：quantum adiabatic interaction 

摘      要：A quantum computer is not necessarily alone,e.g.,thousands and millions of quantum computers are simultaneously working together for adiabatic quantum computers based on nuclear ***-range interaction is inevitable between these nuclear spin *** we investigate the effect of long-range dipolar interaction between different adiabatic quantum *** analytical and numerical results show that the dipolar interaction can enhance the final fidelity in adiabatic quantum computation for solving the factorization problem,when the overall interaction is *** enhancement will become more prominent if a single quantum computer encounters an extremely small energy gap which occurs more likely for larger-size systems.
