The Hamiltonian of a biexciton in a two‐dimensional quantum dot with parabolic confinement has been diagonalized to obtain the low‐lying eigenenergy values as a function of the electron‐to‐hole effective mass ratio and the dot size. Using the present result, a series of magic angular momenta of the biexciton dots have been discovered. Theoretical explanations derived from first principles have been formulated.
