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].}}, author = {{de Beaudrap, Niel and Gharibian, Sevag}}, booktitle = {{Proceedings of the 31st Conference on Computational Complexity (CCC 2016)}}, editor = {{Raz, Ran}}, isbn = {{978-3-95977-008-8}}, keywords = {{quantum 2-SAT, transfer matrix, strongly connected components, limited backtracking, local Hamiltonian}}, location = {{Tokyo, Japan}}, pages = {{27:1--17:21}}, publisher = {{Schloss Dagstuhl - Leibniz-Zentrum fuer Informatik}}, title = {{{A Linear Time Algorithm for Quantum 2-SAT}}}, doi = {{10.4230/LIPIcs.CCC.2016.27}}, volume = {{50}}, year = {{2016}}, } @article{31291, abstract = {{We consider a simple model of an open partially expanding map.

This hypothesis is stable under perturbations and means that the dynamics is univalued in a neighborhood of ${\mathcal{K}}$.

We show that determining how ``connected'' the ground space of a local Hamiltonian is can range from QCMA-complete to PSPACE-complete, as well as NEXP-complete for an appropriately defined ``succinct'' version of the problem. As a result, we obtain a natural QCMA-complete problem, a goal which has generally proven difficult since the conception of QCMA over a decade ago. Our proofs rely on a new technical tool, the Traversal Lemma, which analyzes the Hilbert space a local unitary evolution must traverse under certain conditions.
