Additionally, it 1) is state-independent, 2) involves two-way classical communication, and 3) does not require basis matching between the two parties. The Brukner-Taylor-Cheung-Vedral (BTCV) time-like form of the Bell-CHSH inequality by Bruk and by Tay is employed as an eavesdropping check; sequential measurements lead to an inequality identical in form to the Bell-CHSH inequality, which relies only on the measurements performed with no regard for the qubit states. We show that this form manifests naturally from the non-commutativity of observables.<\/jats:p>","DOI":"10.26421\/qic19.15-16-2","type":"journal-article","created":{"date-parts":[[2021,2,15]],"date-time":"2021-02-15T19:07:06Z","timestamp":1613416026000},"page":"1279-1293","source":"Crossref","is-referenced-by-count":1,"title":["State-independent quantum key distribution with two-way classical communication"],"prefix":"10.26421","volume":"19","author":[{"given":"Radha Pyari","family":"Sandhir","sequence":"first","affiliation":[]}],"member":"10955","published-online":{"date-parts":[[2019,12]]},"container-title":["Quantum Information and Computation"],"original-title":[],"deposited":{"date-parts":[[2021,2,15]],"date-time":"2021-02-15T19:07:09Z","timestamp":1613416029000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.rintonpress.com\/journals\/doi\/QIC19.15-16-2.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12]]},"references-count":0,"journal-issue":{"issue":"15&16","published-online":{"date-parts":[[2019,12]]},"published-print":{"date-parts":[[2019,12]]}},"URL":"https:\/\/doi.org\/10.26421\/qic19.15-16-2","relation":{},"ISSN":["1533-7146","1533-7146"],"issn-type":[{"value":"1533-7146","type":"print"},{"value":"1533-7146","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,12]]}}}
