Despite a lot of progress, the visual tracking problem is still a challenging task due to appearance variations over time. In this paper, ... More
Upper bound of the fully entangled fractionOct 06 2008We study the fully entangled fraction of quantum states. An upper bound is obtained for arbitrary dimensional bipartite systems. This bound is shown to be exact for the case of two-qubit systems. An inequality related the fully entangled fraction of two ... More
Local Unitary Invariants for Multipartite Quantum SystemsOct 23 2014We present an approach of constructing invariants under local unitary transformations for multipartite quantum systems. The invariants constructed in this way can be complement to that in [Science 340 (2013) 1205-1208]. Detailed examples are given to ... More
Probing Quantum Phase Transition in Macroscopic Qubit Array via circuit QED architectureMar 02 2006Jun 06 2006We demonstrate a universal physical mechanism to probe the macroscopic quantum phase transition based on circuit QED architecture. We found that, with certain parameters, the Josephson junction qubit array behaves as an antiferromagnetic Ising model in ... More
Quantization of (1+1)-dimensional Hořava-Lifshitz theory of gravityAug 11 2014Dec 31 2014In this paper, we study the quantization of the (1+1)-dimensional projectable Ho\v{r}ava-Lifshitz (HL) gravity, and find that, when only gravity is present, the system can be quantized by following the canonical Dirac quantization, and the corresponding ...

Extended staggered-flux phases in two-dimensional latticesAug 07 2006Based on the so called $t$-$\phi$ model in two-dimensional (2D) lattices, we investigate the stabilities of a class of extended staggered-flux (SF) phases (which are the extensions of the $\sqrt{2}\times\sqrt{2}$ SF phase to generalized spatial periods) ...
