摘要
In the quantum metrology,applications of quantum techniques based on entanglement bring in some better performances than conventional approaches.We experimentally investigate an application of entanglement in accurate ranging based on the second-order coherence in the time domain.By a fitting algorithm in the data processing,the optimization results show a precision of±200μm at a distance of 1043.3 m.In addition,the influence of jamming noise on the ranging scheme is studied.With some different fitting parameters,the result shows that the proposed scheme has a powerful anti-jamming capability for white noise.
