Even if an instantaneous expectation value of a physical quantity for the adiabatically prepared quantum state is close to an expectation value for the true vacuum, this does not assure us that the prepared vacuum is close to the true vacuum. In general time average of the expectation value tend to systematically differ from the true value. Using a simple model we discuss how to diminish this systematic difference.", "revisions": [ { "version": "v1", "updated": "2021-07-04T22:20:41.000Z" } ], "analyses": { "keywords": [ "adiabatic quantum computation", "true vacuum", "general time average", "expectation value tend", "utilizing quantum states" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
