High-sensitivity and high-resolution collaborative determination of birefringence coefficient using weak measurement
Shuqi Gao, Min Zhang, Jiahui Hou +5
Precise nanofilm birefringence characterization is essential for high-sensitivity polarization response and strong anti-interference detection in photodetectors. We present a high-…

Distributed Privacy Preserving Iterative Summation Protocols
Yang Liu, Qingchen Liu, Xiong Zhang +2
In this paper, we study the problem of summation evaluation of secrets. The secrets are distributed over a network of nodes that form a ring graph. Privacy-preserving iterative pro…

Mapping Target Location from Doppler Data
Qingchen Liu, Samuel P. Drake, Brian D. O. Anderson
In this paper, we present an algorithm for determining a curve on the earth's terrain on which a stationary emitter must lie according to a single Doppler shift measured on an unma…
