Eigenlevel statistics of the quantum adiabatic algorithm
Marko Znidaric
We study the eigenlevel spectrum of quantum adiabatic algorithm for 3-satisfiability problem, focusing on single-solution instances. The properties of the ground state and the asso…
Inelastic scattering of light by a cold trapped atom: Effects of the quantum center-of-mass motion
Marc Bienert, Wolfgang Merkel, Giovanna Morigi
The light scattered by a cold trapped ion, which is in the stationary state of laser cooling, presents features due to the mechanical effects of atom-photon interaction. These feat…
Approximate programmable quantum processors
Mark Hillery, Mario Ziman, Vladimir Buzek
A quantum processor is a programmable quantum circuit in which both the data and the program, which specifies the operation that is carried out on the data, are quantum states. We…
Entanglement-induced state ordering under local operations
Mario Ziman, Vladimir Buzek
We analyze how entanglement between two components of a bipartite system behaves under the action of local channels of the form $\cE\otimes\cI$. We show that a set of maximally ent…
Exponential complexity of an adiabatic algorithm for an NP-complete problem
Marko Znidaric, Martin Horvat
We prove an analytical expression for the size of the gap between the ground and the first excited state of quantum adiabatic algorithm for the 3-satisfiability, where the initial…
Robust state preparation of a single trapped ion by adiabatic passage
Chr. Wunderlich, Th. Hannemann, T. Koerber +5
We report adiabatic passage experiments with a single trapped Ca ion. By applying a frequency chirped laser pulse with a Gaussian amplitude envelope we reach a transfer…
