Sequential Systems of Linear Equations Algorithm for Nonlinear Optimization Problems with General Constraints
In Ref. 1, a new superlinearly convergent algorithm of sequential systems of linear equations (SSLE) for nonlinear optimization problems with inequality constraints was proposed. At each iteration,Expand

  • 24 January 2011
For more than a decade, it was believed that unconditionally secure quantum bit commitment (QBC) is impossible. But based on a previously proposed quantum key distribution scheme using orthogonalExpand

SIMPLE QUANTUM PROTOCOLS FOR THE MILLIONAIRE PROBLEM WITH A SEMI-HONEST THIRD PARTY
TLDR
We propose a new protocol to solve the millionaire problem and private comparison problem by adding a semi-honest third party, which surpass all existing protocols on feasibility and security. Expand

TLDR
We simplified our previously proposed quantum bit commitment (QBC) protocol based on the Mach–Zehnder interferometer, by replacing symmetric beam splitters with asymmetric ones. Expand

TLDR
We propose a novel protocol with a distinct security checking strategy, which still involves single qubitoperations only, making it possible to achieve better security of quantum secret sharingwith current technology. Expand

Secure quantum bit commitment against empty promises
The existence of unconditionally secure quantum bit commitment (QBC) is excluded by the Mayers-Lo-Chau no-go theorem. Here we look for the second-best: a QBC protocol that can defeat certain quantumExpand

Chaos in quantum steering in high-dimensional systems
Quantum steering means that in some bipartite quantum systems, the local measurements on one side can determine the state of the other side. Here we show that in high-dimensional systems, thereExpand

Oblivious transfer using quantum entanglement
Based on quantum entanglement, an all-or-nothing oblivious transfer (OT) protocol is proposed and is proven to be secure. The distinct merit of the present protocol lies in that it is not based onExpand
