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
Mohan Sarovar,Akihito Ishizaki,Akihito Ishizaki,Graham R. Fleming,Graham R. Fleming,K. Birgitta Whaley +5 more
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
Using coherence to enhance function in chemical and biophysical systems

TL;DR: The state of recent discoveries is surveyed, viewpoints that suggest that coherence can be used in complex chemical systems are presented, and the role of coherence as a design element in realizing function is discussed.
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
