In contrast, 2-SAT can not only be decided in polynomial time, but in fact in deterministic linear time. In 2006, Bravyi proposed a physically motivated generalization of k-SAT to the quantum setting, defining the problem \"quantum k-SAT\". He showed that quantum 2-SAT is also solvable in polynomial time on a classical computer, in particular in deterministic time O(n^4), assuming unit-cost arithmetic over a field extension of the rational numbers, where n is number of variables. In this paper, we present an algorithm for quantum 2-SAT which runs in linear time, i.e. deterministic time O(n+m) for n and m the number of variables and clauses, respectively. Our approach exploits the transfer matrix techniques of Laumann et al. [QIC, 2010] used in the study of phase transitions for random quantum 2-SAT, and bears similarities with both the linear time 2-SAT algorithms of Even, Itai, and Shamir (based on backtracking) [SICOMP, 1976] and Aspvall, Plass, and Tarjan (based on strongly connected components) [IPL, 1979]."}],"main_file_link":[{"url":"http://drops.dagstuhl.de/opus/volltexte/2016/5836/","open_access":"1"}],"external_id":{"arxiv":["1508.07338"]},"author":[{"full_name":"de Beaudrap, Niel","first_name":"Niel","last_name":"de Beaudrap"},{"full_name":"Gharibian, Sevag","orcid":"0000-0002-9992-3379","first_name":"Sevag","id":"71541","last_name":"Gharibian"}],"citation":{"ieee":"N. de Beaudrap and S.
