Bivariate Bicycle Codes over Group Algebras
Chaobin Liu
We study a weighted-shift formulation of bivariate bicycle group-algebra (BBGA) codes over finite group algebras. One binary shift acts by right multiplication and the other by lef…
Twisted Fiber Bundle Codes over Group Algebras
Chaobin Liu
We introduce a twisted fiber bundle construction of quantum CSS codes over group algebras \(R=\mathbb F_2[G]\), where each base generator carries a generator-dependent \(R\)-linear…
Exact performance of the five-qubit code with coherent errors
Chaobin Liu
To well understand the behavior of quantum error correction codes (QECC) in noise processes, we need to obtain explicit coding maps for QECC. Due to extraordinary amount of computa…
Wannier-type photonic higher-order topological corner states induced solely by gain and loss
Ya-Jie Wu, Chao-Chen Liu, Junpeng Hou
Photonic crystals have provided a controllable platform to examine excitingly new topological states in open systems. In this work, we reveal photonic topological corner states in…
Probability distributions for Markov chains based quantum walks
Radhakrishnan Balu, Chaobin Liu, Salvador E. Venegas-Andraca
We analyze the probability distributions of the quantum walks induced from Markov chains by Szegedy (2004). The first part of this paper is devoted to the quantum walks induced fro…
Steady states of continuous-time open quantum walks
Chaobin Liu, Radhakrishnan Balu
Continuous-time open quantum walks (CTOQW) are introduced as the formulation of quantum dynamical semigroups of trace-preserving and completely positive linear maps (or quantum Mar…
