摘要：
Anticoherent spin states are introduced as quantum states that exhibit maximally nonclassical behaviors which are important in the study of quantum entanglement. Using Majorana representation of spin states, Crann-Pereira-Kribs studied the relation between anticoherent spin states and spherical designs. They proposed a conjecture that a spin-s state is anticoherent to order t if and only if its Majorana representation is a spherical t-design on S (2). In this paper, we prove that this conjecture is true for s = 2.
