Journal ArticleDOI

Quantum random-walk search algorithm

TL;DR: It will be shown that this algorithm performs an oracle search on a database of N items with $O(\sqrt{N})$ calls to the oracle, yielding a speedup similar to other quantum search algorithms.
Journal ArticleDOI

Quantum entanglement in photosynthetic light-harvesting complexes

TL;DR: In this article, the authors analyzed entanglement in multi-chromophoric light harvesting complexes, and established methods for quantification of entenglement by presenting necessary and sufficient conditions for entanglements and by deriving a measure of global entengement.
Journal ArticleDOI

Geometric theory of nonlocal two-qubit operations

TL;DR: In this article, the geometric structure of non-local gates is shown to be a 3-torus, and the invariants for local transformations are derived from the coordinates of the 3torus.
Journal ArticleDOI

Software for the frontiers of quantum chemistry: An overview of developments in the Q-Chem 5 package

Evgeny Epifanovsky, +238 more
TL;DR: The Q-Chem quantum chemistry program package as discussed by the authors provides a suite of tools for modeling core-level spectroscopy, methods for describing metastable resonances, and methods for computing vibronic spectra, the nuclear-electronic orbital method, and several different energy decomposition analysis techniques.
