Traditionally, QET has only been considered under strict constraints, including the requirements that the initial state be the ground state of an interacting Hamiltonian, that Alice\u2019s measurement commute with the interaction terms, and that entanglement be present. These constraints have significantly limited the broader applicability of QET protocols. In this work, we demonstrate that SLP can arise beyond these conventional constraints, establishing the necessity of QET in a wider range of scenarios for local energy extraction. This leads to a more flexible and generalized framework for QET. Furthermore, we introduce the concept of a \u201clocal effective Hamiltonian,\u201d which eliminates the need for optimization techniques in determining Bob\u2019s optimal energy extraction in QET protocols. As an additional advantage, the amount of energy that can be extracted using our new protocol is amplified to be 7.2 times higher than that of the original protocol. These advancements enhance our understanding of QET and extend its broader applications to quantum technologies. To support our findings, we implement the protocol on quantum hardware, confirming its theoretical validity and experimental feasibility.<\/jats:p>","DOI":"10.3390\/e27111147","type":"journal-article","created":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T09:10:45Z","timestamp":1763025045000},"page":"1147","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Strong Local Passivity in Unconventional Scenarios: A New Protocol for Amplified Quantum Energy Teleportation"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9136-9481","authenticated-orcid":false,"given":"Songbo","family":"Xie","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, North Carolina State University, Raleigh, NC 27606, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7436-5422","authenticated-orcid":false,"given":"Manas","family":"Sajjan","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, North Carolina State University, Raleigh, NC 27606, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0574-5346","authenticated-orcid":false,"given":"Sabre","family":"Kais","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, North Carolina State University, Raleigh, NC 27606, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1895","DOI":"10.1103\/PhysRevLett.70.1895","article-title":"Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels","volume":"70","author":"Bennett","year":"1993","journal-title":"Phys.
