A proposal to generate entangled compass states with sub‐Planck structure
S Choudhury, PK Panigrahi - AIP Conference Proceedings, 2011 - pubs.aip.org
We illustrate a procedure to generate a bipartite, entangled compass state, which shows sub‐
Planck structure. The proposed method uses the interaction of a standing wave laser field,
with two, two‐level atoms and relies on the ability of this system to choose certain
mesoscopic bipartite states to couple with the internal degrees of freedom. An appropriate
measurement on the internal degrees of freedom then leads to the entangled state, which
shows sub‐Planck structures, desired for quantum metrology.
