In this paper, we investigate whether their resonant structure permits compact quantum-compatible encoding. Transfer functions from the Dresden Vocal Tract Dataset are represented as 14-qubit amplitude states and compressed using matrix product states. The resulting states exhibit low cross-partition complexity, allowing a bond-dimension-eight representation to reduce storage by 13.7 times while retaining reconstruction accuracy close to the uncompressed finite-element reference. A complex encoding also preserves phase. These findings show how acoustic structure can reduce the memory required for sequential preparation of quantum-encoded speech representations.<\/jats:p>","DOI":"10.1121\/10.0046484","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T16:01:51Z","timestamp":1790092911000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Matrix-product-state compression of quantum-encoded vocal-tract transfer functions"],"prefix":"10.1121","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7636-3797","authenticated-orcid":false,"given":"Sheng","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Science Tokyo 1 , Yokohama, Kanagawa 226-8501,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4997-3850","authenticated-orcid":false,"given":"Jiyi","family":"Li","sequence":"additional","affiliation":[{"name":"Hokkaido University 2 , Sapporo, Hokkaido 060-0814,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"2026092212014514000_c1","volume-title":"Acoustic Theory of Speech Production: With Calculations Based on X-Ray Studies of Russian Articulations","year":"1960"},{"key":"2026092212014514000_c2","volume-title":"Acoustic Phonetics","year":"1998"},{"issue":"14","key":"2026092212014514000_c3","doi-asserted-by":"publisher","first-page":"147902","DOI":"10.1103\/PhysRevLett.91.147902","article-title":"Efficient classical simulation of slightly entangled quantum computations","volume":"91","year":"2003","journal-title":"Phys.
