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…
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…
Optimum pulse shapes for stimulated Raman adiabatic passage
G. S. Vasilev, A. Kuhn, N. V. Vitanov
Stimulated Raman adiabatic passage (STIRAP), driven with pulses of optimum shape and delay has the potential of reaching fidelities high enough to make it suitable for fault-tolera…
