Nomination text:
This publication was selected as a highlight in nanotechnology for it's clear description of DiVincenzo's criteria, the challenges associated with each, and describing the merit endohedral fullerene's have for each criterion. In this work Twamley describes how 15N@60C0 and 31P@C60 and other Group-V endohedral materials behave as electrostatically isolated atom traps that can be manipulated with STM techniques, and that can be self-assembled. Further more, the author describes the relatively long electronic decoherence times for these molecular qubits, and techniques to entangle adjacent systems via inter-molecule magnetic dipole interactions, further staving system decoherence. Finally, the author argues that qubit readout can be achieved utilizing NMR and ESR science, which is of crucial importance for their implementation in a quantum information processor.
