We present a rigorous proof of an interesting boundary effect of deterministic dense coding first observed by S. Mozes, J. Oppenheim, and B. Reznik [Phys. Rev. A 71, 012311 (2005)]. Namely, it is shown that d2 -1 cannot be the maximal alphabet size of any isometric deterministic dense coding schemes utilizing d -level partial entanglement. © 2006 The American Physical Society.
