    "abstract": "A controlled quantum dense coding scheme is investigated with a four-particle\nnon-maximal quantum channel. The amount of classical information is shown to be\ncapable of being controlled by the controllers through adjustments of the local\nmeasurement angles and to depend on the coefficients of the quantum channel; in\naddition, the four particles are distributed in two inverse ways in such an\nquantum channel. A restricted condition for distributing the particles to\nrealize quantum dense coding in an arbitrary ($N+2$)-particle quantum channel\nis proposed.",
