Quantum walks in the wild: perfect quantum state transfer with superconducting qubits

Abstract:

Superconducting quantum bits are artificial atoms that can be wired  up into complex structures.  I will present a theoretical proposal to  implement perfect quantum state transfer between any two nodes of a hypercube  network.  This example of novel quantum transport in an artificial solid has many  applications for quantum computing.  It would also provide an experimental  simulation of a continuous-time quantum walk with exponential speedup over the corresponding classical walk.  This speedup is found to be  remarkably robust to both decoherence and diagonal disorder, but only for certain  (inefficient) representations of the hypercube.
