【摘要】 本文利用确定量子态过滤的方法,评价了奇偶相干态的去相干通道的敏感性。发现奇相干态探测场要比偶相干态探测场对去相干性更敏感。同时也发现精确限制的渐进行为和其他探测场的行为一样。更多还原

【Abstract】 In this paper, we apply unambiguous quantum state filtering to evaluation of the sensing decoherence channel for odd and even coherent probe states. We find that odd coherent probe showed better performance than even coherent probe. We also find that the asymptotic behavior of the precision limit is the same as that of other probe fields.更多还原
