Quantum Spin Holography with Surface State Electrons
In a recent paper Moon and coworkers [C.R. Moon et al., Nature Nanotechnology
4, 167 (2009)] have shown that the single-atom limit for information storage
density can be overcome by using the coherence of electrons in a
two-dimensional electron gas to produce quantum holograms comprised of
individually manipulated molecules projecting an electronic pattern onto a
portion of a surface. We propose to further extend the concept by introducing
quantum spin holography - a version of quantum holographic encoding allowing to
store the information in two spin channels independently.Comment: 5 pages, 3 figure
