These derivations are intended to clarify the interpretation of SQL's in the context of continuous quantum measurement.", "revisions": [ { "version": "v3", "updated": "1998-01-28T18:13:21.000Z" } ], "analyses": { "keywords": [ "standard quantum limit", "broadband position measurement", "weak classical force", "continuous position measurements", "free mass" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
