中文摘要	we present a modified method for detecting the concurrence in an arbitrary two-qubit quantum state rho(ab) with local operations and classical communication. in this method, it is not necessary for the two observers to prepare the quantum state rho(ab) by the structural physical approximation. their main task is to measure four specific functions via two local quantum networks. with these functions they can determine the concurrence and then the entanglement of formation.
