1 May 2016 | Abstract: | We construct Einstein-Podolsky-Rosen (EPR) steering signatures for the
nonlocality of the entangled "Schrodinger cat-type" superposition state
described by $frac{1}{sqrt{2}}{|N
angle|0
angle+|0
angle|N
angle}$,
often called the NOON state. The signatures are a violation of an EPR steering
inequality based on an uncertainty relation. The violation confirms a
generalised EPR paradox, or "EPR steering", between the two modes and involves
certification of an inter-mode correlation for both number and quadrature phase
amplitude observables. We also explain how the signatures certify an $N$th
order quantum coherence, so the system (for larger $N$) can be signified to be
in a "cat" superposition of mesoscopically distinct states. Realisation for
larger $N>1$ would thus give evidence of mesoscopic EPR steering and
entanglement. We include treatment of nonideal cases. Finally, we examine the
limitations imposed for lossy scenarios, discussing how experimental
realisations may be possible for $N=2,3$. | Source: | arXiv, 1605.0221 | Services: | Forum | Review | PDF | Favorites |
