This instrument confines ion chains using a surface electrode trap with a two-dimensional magneto-optical trap as an atomic source. Several laser systems spanning 400\u20131100\u00a0nm are used to achieve high-fidelity state preparation and readout. Photons are produced via the decay of an exited state, which is accessed using a custom 408\u00a0nm laser system that produces 150\u00a0ps optical pulses using non-linear photonics. We demonstrate single-photon production through a Hanbury Brown\u2013Twiss measurement for one to six ions.<\/jats:p>","DOI":"10.1063\/5.0288146","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T13:44:18Z","timestamp":1767879858000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["88Sr+ ion trap apparatus for generating 408\u00a0nm photons"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2111-6144","authenticated-orcid":false,"given":"Jianlong","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Illinois Urbana-Champaign 1 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7817-8695","authenticated-orcid":false,"given":"Mari","family":"Cieszynski","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois Urbana-Champaign 2 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1908-4810","authenticated-orcid":false,"given":"William","family":"Christopherson","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois Urbana-Champaign 2 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0882-3290","authenticated-orcid":false,"given":"Darman","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois Urbana-Champaign 2 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5566-8599","authenticated-orcid":false,"given":"Lintao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois Urbana-Champaign 2 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6553-9731","authenticated-orcid":false,"given":"Elizabeth","family":"Goldschmidt","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois Urbana-Champaign 2 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2791-0413","authenticated-orcid":false,"given":"Brian","family":"DeMarco","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Illinois Urbana-Champaign 2 , Urbana, Illinois 61801,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2026,1,8]]},"reference":[{"key":"2026010808441429700_c1","doi-asserted-by":"publisher","first-page":"771","DOI":"10.1002\/1521-3978(200009)48:9\/11&lt;771::aid-prop771&gt;3.0.co;2-e","article-title":"The physical implementation of quantum computation","volume":"48","year":"2000","journal-title":"Fortschr.
