Pretty good state transfer between internal nodes of paths
Gabriel Coutinho, Krystal Guo, Christopher M. van Bommel
We study a continous-time quantum walk on a path graph. In this paper, we show that, for any odd prime and positive integer , the path on vertices admits pretty…

Pretty Good State Transfer in Qubit Chains - The Heisenberg Hamiltonian
Leonardo Banchi, Gabriel Coutinho, Chris Godsil +1
Pretty good state transfer in networks of qubits occurs when a continuous-time quantum walk allows the transmission of a qubit state from one node of the network to another, with f…

Perfect state transfer is poly-time
Gabriel Coutinho, Chris Godsil
We show that deciding whether a graph admits perfect state transfer can be done in polynomial time with respect to the size of the graph on a classical computer.
