| 中文摘要 | we present a parametrically efficient method for measuring the entanglement of formation e-f in an arbitrarily given unknown two-qubit state rho(ab) by local operations and classical communication. the two observers, alice and bob, first perform some local operations on their composite systems separately, by which the desired global quantum states can be prepared. then they estimate seven functions via two modified local quantum networks supplemented a classical communication. after obtaining these functions, alice and bob can determine the concurrence c and the entanglement of formation e-f. |
