Submitted for the MAR14 Meeting of The American Physical Society Avoiding Loopholes with Hybrid Bell-Leggett-Garg Inequalities JUSTIN DRESSEL, ALEXANDER KOROTKOV, Univ of California Riverside — By combining the postulates of macrorealism with Bell-locality, we derive a qualitatively different hybrid inequality that avoids two loopholes that commonly appear in Leggett-Garg and Bell inequalities. First, locally-invasive measurements can be used, which avoids the “clumsiness” Leggett-Garg inequality loophole. Second, a single experimental ensemble with fixed analyzer settings is sampled, which avoids the “disjoint sampling” Bell inequality loophole. The derived hybrid inequality has the same form as the Clauser-Horne-Shimony-Holt Bell inequality; however, its quantum violation intriguingly requires weak measurements. A realistic explanation of an observed violation requires either the failure of Bell-locality, or a preparationconspiracy of finely tuned and nonlocally-correlated noise. Modern superconducting and optical implementations of this test are considered. Justin Dressel Univ of California Riverside Date submitted: 07 Nov 2013 Electronic form version 1.4

متن کاملLeggett-Garg Inequalities for Squeezed States
Temporal Bell inequalities, or Leggett-Garg Inequalities (LGI), are studied for continuous-variable systems placed in a squeezed state. The importance of those systems lies in their broad applicability which allows the description of many different physical settings in various branches of physics, ranging from cosmology to condensed matter physics and from optics to quantum information theory. ...
