Quantum fractional revival

I will introduce continuous-time quantum walks, with some motivation and examples. Following, we shall discuss several interesting cases in which a quantum walk reaches some specific quantum states. We shall pay extra attention to what has been known as fractional revival. I will talk about some recent advances made by several colleagues and myself, as well as some of the interesting problems that are still open. This talk will contain moving pictures, and will be at level someone with no prior knowledge about quantum walks shall be able to follow.
