摘要

Relations between teleportation, Bell's inequalities and inseparability are investigated. It is shown that any mixed two spin- $1\over2$ state which violates the Bell-CHSH inequality is useful for teleportation. The result is extended to any Bell's inequalities constructed of the expectation values of products of spin operators. It is also shown that there exist inseparable states which are not useful for teleportation within the standard scheme.
