Pretty good state transfer among large sets of vertices
Ada Chan, Peter Sin
In a continuous-time quantum walk on a network of qubits, pretty good state transfer is the phenomenon of state transfer between two vertices with fidelity arbitrarily close to 1.…
Large sets of strongly cospectral vertices in Cayley graphs
Peter Sin
Strong cospectrality is an equivalence relation on the set of vertices of a graph that is of importance in the study of quantum state transfer in graphs. We construct families of a…
Continuous-time Quantum Walks on Cayley Graphs of Extraspecial Groups
Peter Sin, Julien Sorci
We study continuous-time quantum walks on normal Cayley graphs of certain non-abelian groups, called extraspecial groups. By applying general results for graphs in association sche…
All -transitive groups have the EKR-module property
Karen Meagher, Peter Sin
We prove that every 2-transitive group has a property called the EKR-module property. This property gives a characterization of the maximum intersecting sets of permutations in the…
Linear representations of finite geometries and associated LDPC codes
Peter Sin, Julien Sorci, Qing Xiang
The {\it linear representation} of a subset of a finite projective space is an incidence system of affine points and lines determined by the subset. In this paper we use character…
The critical group of the Kneser graph on -subsets of an -element set
Joshua E. Ducey, Ian Hill, Peter Sin
In this paper we compute the critical group of the Kneser graph . This is equivalent to computing the Smith normal form of a Laplacian matrix of this graph.
