文摘

A detailed study of entanglement in three-spin superposition of SU(2) coherent states is presented. Explicit expressions to quantify the entanglement of three-spin states for both W and GHZ classes are given. According to the numerical study of entanglement behavior of the system, the states are separated into two integer and half-integer spin classes. Even though entanglement behavior of integer and half-integer spin states are different, entanglement increases by increasing spin in both W and GHZ classes. Moreover, the conditions under which three spin system states become maximally entangled in both classes are given.
