Robustness of the adiabatic quantum search
Johan Åberg, David Kult, Erik Sjöqvist
The robustness of the local adiabatic quantum search to decoherence in the instantaneous eigenbasis of the search Hamiltonian is examined. We demonstrate that the asymptotic time-c…

Searching for degeneracies of real Hamiltonians using homotopy classification of loops in SO()
Niklas Johansson, Erik Sjöqvist
Topological tests to detect degeneracies of Hamiltonians have been put forward in the past. Here, we address the applicability of a recently proposed test [Phys. Rev. Lett. {\bf 92…

Effect of intersubsystem coupling on the geometric phase in a bipartite system
X. X. Yi, Erik Sjöqvist
The influence of intersubsystem coupling on the cyclic adiabatic geometric phase in bipartite systems is investigated. We examine the geometric phase effects for two uniaxially cou…
