The problem of packing circles into a domain of prescribed topology is considered. The circles need not have equal radii. The Collins-Stephenson algorithm computes such a circle packing. This algorithm is parMlelized in two different ways and its performance is reported for a triangular, planar domain test case. The implementation uses the highly parallel graphics processing unit （GPU） on commodity hardware. The speedups so achieved are discussed based on a number of experiments.

Improving the security of “measurement-device-independent quantum communication without encryption”

引用

Science Bulletin 2020年第24期65卷 2048-2049,M0004页

作者： Nayana Das Goutam paul Applied Statistics Unit Indian Statistical InstituteKolkataIndia Cryptology and Security Research Unit R.C.Bose Centre for Cryptology and SecurityIndian Statistical InstituteKolkataIndia

In 2018, Niu et al. [1] proposed a measurement-device-independent quantum secure direct communication(MDI-QSDC) protocol and quantum dialogue(MDI-QD) protocol using Einstein-Podolsky-rosen(EPR) pairs. In their protocols, the two legitimate parties prepare two sets of EPR pairs in their locations, and send the partner qubits of their EPR pairs to an untrusted third party(UTP). Here we analyze these protocols and show that 50% of the information about the secret message bits is leaked out in both the protocols.
