摘要

报告摘要:In addition to providing support for standards and units, precision measurement erects limits for established laws and theories governing the nature. Statistical inference of a parameter from measurements on an ensemble of independent particles is lower bounded by the classical precision limit or the standard quantum limit (SQL). A number of quantum enhanced measurement paradigms are introduced, and illustrative experiments carried out with Bose-Einstein condensed atoms. Deterministically generated entangled atomic ensembles are applied in linear interferometry with reduced quantum noise, time reversed quantum interactions are engineered for nonlinear interferometry to amplify signal, both demonstrating precisions beyond SQL.
