Extremal states of positive partial transpose in a system of three qubits
Øyvind Steensgaard Garberg, Børge Irgens, Jan Myrheim
We have studied mixed states in the system of three qubits with the property that all their partial transposes are positive, these are called PPT states. We classify a PPT state by…
Cavity QED simulation of qubit-oscillator dynamics in the ultrastrong coupling regime
Arne L. Grimsmo, Scott Parkins
We propose a quantum simulation of a two-level atom coupled to a single mode of the electromagnetic field in the ultrastrong-coupling regime based upon resonant Raman transitions i…
Error Estimation, Error Correction and Verification In Quantum Key Distribution
Øystein Marøy, Magne Gudmundsen, Lars Lydersen +1
We consider error correction in quantum key distribution. To avoid that Alice and Bob unwittingly end up with different keys precautions must be taken. Before running the error cor…
Memory Effects in Spontaneous Emission Processes
Arne L. Grimsmo, Asle H. Vaskinn, Per K. Rekdal +1
We consider a quantum-mechanical analysis of spontaneous emission in terms of an effective two-level system with a vacuum decay rate and transition angular frequency . O…
Sign of the Casimir-Polder interaction between atoms and oil-water interfaces: Subtle dependence on dielectric properties
Mathias Boström, Simen Å. Ellingsen, Iver Brevik +2
We demonstrate that Casimir-Polder energies between noble gas atoms (dissolved in water) and oil-water interfaces are highly surface specific. Both repulsion (e.g. hexane) and attr…
Ultrathin Metallic Coatings Can Induce Quantum Levitation between Nanosurfaces
Mathias Boström, Barry W. Ninham, Iver Brevik +3
There is an attractive Casimir-Lifshitz force between two silica surfaces in a liquid (bromobenze or toluene). We demonstrate that adding an ultrathin (5-50Å) metallic nanocoating…
Dynamics of genuine multipartite correlations in open quantum systems
Arne L. Grimsmo, Scott Parkins, Bo-Sture K. Skagerstam
We propose a measure for genuine multipartite correlations suited for the study of dynamics in open quantum systems. This measure is contextual in the sense that it depends on how…
Higher-order Brunnian structures and possible physical realizations
Nils A. Baas, D. V. Fedorov, A. S. Jensen +3
We consider few-body bound state systems and provide precise definitions of Borromean and Brunnian systems. The initial concepts are more than a hundred years old and originated in…
Casimir Friction Force Between Polarizable Media
Johan S. Høye, Iver Brevik
This work is a continuation of our recent series of papers on Casimir friction, for a pair of particles of low relative particle velocity. Each particle is modeled as a simple harm…
Casimir-Lifshitz interaction between ZnO and SiO2 nanorods in bromobenzene: retardation effects turn the interaction repulsive at intermediate separations
Mathias Boström, Bo E. Sernelius, Gustavo Baldissera +2
We consider the interaction between a ZnO nanorod and a SiO2 nanorod in bromobenzene. Using optical data for the interacting objects and ambient we calculate the force - from short…
Retardation turns the van der Waals attraction into Casimir repulsion already at 3 nm
Mathias Boström, Bo E. Sernelius, Iver Brevik +1
Casimir forces between surfaces immersed in bromobenzene have recently been measured by Munday et al. Attractive Casimir forces were found between gold surfaces. The forces were re…
Casimir Theory of the Relativistic Composite String Revisited, and a Formally Related Problem in Scalar QFT
Iver Brevik
The main part of this paper is to present an updated review of the Casimir energy at zero and finite temperature for the transverse oscillations of a piecewise uniform closed strin…
