We propose an optimization method to find the quantum circuit for implementing the simultaneous dense coding protocol. This method adopts simulated annealing for optimizing the types and positions of quantum gates, and adopts gradient-based optimization for determining the optimal values of the parameters of quantum gates. The gates are chosen from a given quantum gate set which contains one- and two-qubit fundamental gates. Numerical results demonstrate the practicability of our method. Perfect solutions for simultaneous dense coding with 2 and 3 receivers are found.
