Theoretical analysis of perfect quantum state transfer with superconducting qubits
arXiv:0708.0577 · doi:10.1103/PhysRevB.78.094516
Abstract
Superconducting quantum circuits, fabricated with multiple layers, are proposed to implement perfect quantum state transfer between nodes of a hypercube network. For tunable devices such as the phase qubit, each node can transmit quantum information to any other node at a constant rate independent of the distance between qubits. The physical limits of quantum state transfer in this network are theoretically analyzed, including the effects of disorder, decoherence, and higher-order couplings.
