1263 本文针对该问题，提出一种可有效提取信号峰值频率信息的快速算法，进而实现连续毫米波雷达的快速准确测速测距。 a fast algorithm to extract the peak of signal frequency information is proposed, by which high-efficiency and high-precision meas-urements of the speed and distance for continuous millimeter wave radar is realized.
1264 该算法借助压缩感知原理，通过构建欠定方程，并计算少量内积，实现高效捕捉信号频率值。 By means of the principle of compressedsensing, an underdetermined equation is constructed in the algorithm, and with a few inner product, the frequency correspond-ing to the actual spectral peak of the intermediate frequency signal is captured at a low computational complexity level.
1265 数值结果表明，此算法具有运算量小、计算精度高等特点，可为当今智能交通领域中的高精度测速测距提供一种快速解决方案。 Nu-merical results show that the algorithm can obtain an accurate calculation result with small calculation amount, thus providing a fast solution for high-precision speed measurement and ranging in the field of intelligent transportation.
1266 量子资源理论研究的一个中心问题是为具体的资源提供操作性解释， In the study of quantum resource theories, one of the central problems is to provide an operational meaning for a given resource.
1267 即在完成某种量子信息处理任务时资源态比任何非资源态更有优势。 In the provided quantum information processing task, every resource state provides an advantage com-pared to the case where all resourceless states are used.
1268 最近，Theurer 等人［T Theurer，et al.Phys Rev Lett 119，230401 (2017)］通过扩展相干资源理论建立了严格的叠加资源理论框架。 Recently, Theurer et al. ［T Theurer, et al. Phys Rev Lett 119, 230401(2017)］introduced a rigorous resource theory framework for the quantification of superposition through generalizing of re-source theories of coherence.
1269 在叠加资源理论框架下，本文利用 Holevo-Helstrom 定理定量地刻画单量子比特叠加态在不同类型的量子操作区分任务中的优势， Under the framework, we show that every one-qubit superposition state provides an advantagein different channel discrimination, quantified in terms of the Holevo-Helstrom theorem.
1270 即计算得到叠加态辅助量子操作区分的最大成功概率大于非叠加态辅助时的值。 Then, the maximum probability of success in superposition-assisted channel discrimination has been calculated, which is larger than the value of maximumprobability of success in no superposition-assisted channel discrimination.
1271 这些定量结果还表明，在相同的叠加态辅助下，不同类型的操作(自由操作与非自由操作)之间最易于区分， Our results contribute to understanding the discrim-ination relevance of channels:assisting by the unique coherent state, different kinds of channels are most distinguishable,
1272 而相同类型的量子操作之间，非自由操作之间的区分易于自由操作的区分。这一结果为新型量子安全通信协议的设计提供了新的依据。 and different coherent channels are more distinguishable than different incoherent channels.
