文摘We construct bound entangled states that are entangled but from which no entanglement can De olstilled It all parues are allowed only by performing local operations and classical communications. Moreover, as applications, a detailed example is presented. This example can illuminate that the fidelity of transmission using a bound entangled state is not bigger than a classical scheme.
