报告摘要

Graph theory is important in information theory. We introduce a quantization process on graphs and apply the quantized graphs in quantum information. The quon language provides a mathematical theory to study such quantized graphs in a general framework. We give a new method to construct graphical quantum error correcting codes on quantized graphs and characterize all optimal ones. We establish a further connection to geometric group theory and construct quantum low-density parity-check stabilizer codes on the Cayley graphs of groups. Their logical qubits can be encoded by the ground states of newly constructed exactly solvable models with translation-invariant local Hamiltonians. Moreover, the Hamiltonian is gapped in the large limit when the underlying group is infinite.

会议简介

会议题目：拓扑量子计算2019会议（TQC2019）会议时间：2019-12-16会议地点：深圳主办方：南方科技大学、鹏城实验室
Topological quantum computing (TQC) represents one of the best approaches to building a large-scale fault-tolerant quantum computer. The key for realizing TQC lies in the existence and manipulation of topological phases of matter. Topology, classical or quantum, is central in studying the mathematical theory of such phases. Alternatively, tensor categories and their higher dimensional generalizations give the algebraic characterizations. The conference is on all theoretical aspects that are loosely related to TQC. Interested topics include, but are not limited to, topological phases of matter, tensor/higher categories, subfactor theory, topological quantum field theories, conformal field theories, quantum error correction, entanglement, etc.
