Target Defense Against Link-Prediction-Based Attacks via Evolutionary PerturbationsSep 16 2018In social networks, by removing some target-sensitive links, privacy protection might be achieved. However, some hidden links can still be re-observed by link prediction methods on observable networks. In this paper, the conventional link prediction method ... More
Non-adiabatic geometric quantum computation with trapped ionsApr 05 2002Feb 13 2003We propose a non-adiabatic scheme for geometric quantum computation with trapped ions. By making use of the Aharonov-Anandan phase, the proposed scheme not only preserves the globally geometric nature in quantum computation, but also provides the advantage ... More
Holistic 3D Scene Parsing and Reconstruction from a Single RGB ImageAug 07 2018We propose a computational framework to jointly parse a single RGB image and reconstruct a holistic 3D configuration composed by a set of CAD models using a stochastic grammar model. Specifically, we introduce a Holistic Scene Grammar (HSG) to represent ... More
Integrable Open Spin Chains from Flavored ABJM TheoryApr 19 2017Apr 27 2017We compute the two-loop anomalous dimension matrix in the scalar sector of planar ${\cal N}=3$ flavored ABJM theory. Using coordinate Bethe ansatz, we obtain the reflection matrix and confirm that the boundary Yang-Baxter equations are satisfied. This ... More
