# Fractional revival on non-cospectral vertices

@inproceedings{Godsil2021FractionalRO, title={Fractional revival on non-cospectral vertices}, author={Chris D. Godsil and Xiaohong Zhang}, year={2021} }

Perfect state transfer and fractional revival can be used to move information between pairs of vertices in a quantum network. While perfect state transfer has received a lot of attention, fractional revival is newer and less studied. One problem is to determine the differences between perfect state transfer and fractional revival. If perfect state transfer occurs between two vertices in a graph, the vertices must be cospectral. Further if there is perfect state transfer between vertices a and b…
