Quantum Games and Quantum Strategies
We investigate the quantization of non-zero sum games. For the particular case of the Prisoners' Dilemma we show that this game ceases to pose a dilemma if quantum strategies are allowed for. We alsoExpand
Quantum entanglement
Entanglement is a fundamental resource in quantum information theory. It allows performing new kinds of communication, such as quantum teleportation and quantum dense coding. It is an essentialExpand
Optimization of entanglement witnesses
An entanglement witness (EW) is an operator that allows to detect entangled states. We give necessary and sufficient conditions for such operators to be optimal, i.e. to detect entangled states in anExpand
Ultracold Atoms in Optical Lattices: Simulating quantum many-body systems
1. Introduction 2. Statistical physics of condensed matter: basic concepts 3. Ultracold gases in optical lattices: Basic concepts 4. Quantum simulators of condensed matter 5. Bose Hubbard models:Expand
Thermodynamics from Information
Thermodynamics and information have intricate inter-relations. The justification of the fact that information is physical, is done by inter-linking information and thermodynamics – through Landauer’sExpand
The physics of dipolar bosonic quantum gases
This paper reviews the recent theoretical and experimental advances in the study of ultra-cold gases made of bosonic particles interacting via the long-range, anisotropic dipole–dipole interaction,Expand
Dark solitons in bose-einstein condensates
Dark solitons in cigar-shaped Bose-Einstein condensates of ${}^{87}\mathrm{Rb}$ are created by a phase imprinting method. Coherent and dissipative dynamics of the solitons has been observed.
Classification of mixed three-qubit states.
We introduce a classification of mixed three-qubit states, in which we define the classes of separable, biseparable, W, and Greenberger-Horne-Zeilinger states. These classes are successively embeddedExpand
Ultracold atomic gases in optical lattices: mimicking condensed matter physics and beyond
We review recent developments in the physics of ultracold atomic and molecular gases in optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard models, and as suchExpand
Dynamics of Bose-Einstein condensates: Variational solutions of the Gross-Pitaevskii equations
A variational technique is applied to solve the time-dependent nonlinear Schrodinger equation ~Gross- Pitaevskii equation! with the goal to model the dynamics of dilute ultracold atom clouds in theExpand
