Title: Quantum State Transfer
|Speaker:||Christopher van Bommel|
|Affilliation:||University of Waterloo|
Many quantum algorithms may be modeled as a quantum process occurring on a graph. We interpret quantum channels implemented by spin chains as wires for transmission of states. A major goal of quantum communication is to transfer states with high fidelity. At the maximum fidelity of 1, we say we can achieve perfect state transfer; if fidelities arbitrarily close to 1 can be obtained, we say we can achieve pretty good state transfer. We discuss perfect and pretty good state transfer on paths.
