The asymptotic Schottky problem
Lizhen Ji, Enrico Leuzinger
Let denote the moduli space of compact Riemann surfaces of genus and let be the space of principally polarized abelian varieties of (complex) dime…
Incoherent Control of Locally Controllable Quantum Systems
Daoyi Dong, Chenbin Zhang, Herschel Rabitz +2
An incoherent control scheme for state control of locally controllable quantum systems is proposed. This scheme includes three steps: (1) amplitude amplification of the initial sta…
Integrated Design and Implementation of Embedded Control Systems with Scilab
Longhua Ma, Feng Xia, Zhe Peng
Embedded systems are playing an increasingly important role in control engineering. Despite their popularity, embedded systems are generally subject to resource constraints and it…
Fidelity susceptibility for SU(2)-invariant states
Xiaoguang Wang, Shi-Jiang Gu
We study the fidelity susceptibility of two SU(2)-invariant reduced density matrices. Due to the commuting property of these matrices, analytical results for reduced fidelity susce…
Group Divisible Codes and Their Application in the Construction of Optimal Constant-Composition Codes of Weight Three
Yeow Meng Chee, Gennian Ge, Alan C. H. Ling
The concept of group divisible codes, a generalization of group divisible designs with constant block size, is introduced in this paper. This new class of codes is shown to be usef…
Operator fidelity susceptibility, decoherence and quantum criticality
Xiao-Ming Lu, Zhe Sun, Xiaoguang Wang +1
The extension of the notion of quantum fidelity from the state-space level to the operator one can be used to study environment-induced decoherence. state-dependent operator fideli…
