Design of quantum Fourier transforms and quantum algorithms by using circulant Hamiltonians
B. T. Torosov, N. V. Vitanov
We propose a technique for design of quantum Fourier transforms, and ensuing quantum algorithms, in a single interaction step by engineered Hamiltonians of circulant symmetry. The…
Maximum Cliques in Protein Structure Comparison
Noël Malod-Dognin, Rumen Andonov, Nicola Yanev
Computing the similarity between two protein structures is a crucial task in molecular biology, and has been extensively investigated. Many protein structure comparison methods can…
Simple implementation of a quantum search with trapped ions
Svetoslav S. Ivanov, Peter A. Ivanov, Nikolay V. Vitanov
We propose an ion trap implementation of Grover's quantum search algorithm for an unstructured database of arbitrary length N. The experimental implementation is appealingly simple…
Degenerate Landau-Zener model: Exact analytical solution
G. S. Vasilev, S. S. Ivanov, N. V. Vitanov
The exact analytical solution of the degenerate Landau-Zener model, wherein two bands of degenerate energies cross in time, is presented. The solution is derived by using the Morri…
Strings on the deformed T^{1,1}: giant magnon and single spike solutions
H. Dimov, M. Michalcik, R. C. Rashkov
In this paper we find giant magnon and single spike string solutions in a sector of the gamma-deformed conifold. We examine the dispersion relations and find a behavior analogous t…
Towards a Unifying View of QoS-Enhanced Web Service Description and Discovery Approaches
Dessislava Petrova-Antonova, Sylvia Ilieva
The number of web services increased vastly in the last years. Various providers offer web services with the same functionality, so for web service consumers it is getting more com…
