Phase-matching quantum-key distribution(PM-QKD)has achieved significant results in various practical applications.However,real-time communication requires dynamic adjustment and optimization of key parameters during c...
In our published letter,[1]we have identified a minor error in Figs.2 and 3.Instead,we have 2111 events in these two plots with 646,249,382,and 834 events in Run 9(20.0 ton·day),Run 10(19.4 ton·day),Run 11–1(24.2 ...

In our previous papers we have studied the production of a single hole in the photon number distribution of a field state [Phys. Lett. A 240 (1998) 277;253 (1999) 123]. In this letter we extend the procedure for the c...
We have deposited W/Si multilayer mirrors using magnetron sputtering, and measured their reflectivity at the Beijing Synchrotron Radiation Facility. The W/Si multilayer mirrors show a peak reflectivity of approximatel...

In this letter the scaling properties of the period-adding sequences in a so-called“multiple Devil’s staircase”are reported.It is certified both analytically and numerically that the width of the i-th phase-locked ...
In this letter,a new recursive algorithm to implement phase retrieval from two intensities in the two-dimensional Fourier transform domain is presented.In terms of the cascading property and additivity of the order of...
Twelve new features from our Raman measurements of C_(70) have been observed by using the silver surface enhanced Raman scattering substrate with very high enhanced factor and highly sensitive Raman set.The results an...
