摘要：

We present an entanglement analysis protocol on entangled electron spins using quantum dot (QD) and microcavity coupled system. Each quantum dot is placed in the microcavity and ancilla photon input-output process could be used to check the parity of the quantum dots. After the parity check process, the user only needs to measure the spin direction of the QD spin, and the state information can be readout completely. The feasibility of our scheme and the experimental challenge are discussed by considering currently available techniques.
