Quantum Games and Quantum Strategies

- J. Eisert, M. Wilkens, M. Lewenstein
- Physics
- 26 June 1998

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 also… Expand

Quantum entanglement

- M. Lewenstein
- 2005

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 essential… Expand

Optimization of entanglement witnesses

- M. Lewenstein, B. Kraus, J. Cirac, P. Horodecki
- Physics
- 2 May 2000

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 an… Expand

Ultracold Atoms in Optical Lattices: Simulating quantum many-body systems

- M. Lewenstein, A. Sanpera, V. Ahufinger
- Physics
- 4 May 2012

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

- M. N. Bera, A. Winter, M. Lewenstein
- Mathematics, Physics
- 25 May 2018

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’s… Expand

The physics of dipolar bosonic quantum gases

- T. Lahaye, C. Menotti, L. Santos, M. Lewenstein, T. Pfau
- Physics
- 4 May 2009

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

- S. Burger, K. Bongs, +5 authors M. Lewenstein
- Physics
- 29 October 1999

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.

- A. Acín, D. Bruß, M. Lewenstein, A. Sanpera
- Mathematics, Medicine
- Physical review letters
- 7 March 2001

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 embedded… Expand

Ultracold atomic gases in optical lattices: mimicking condensed matter physics and beyond

- M. Lewenstein, A. Sanpera, V. Ahufinger, B. Damski, Aditi Sen(de), U. Sen
- Physics
- 29 June 2006

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 such… Expand

Dynamics of Bose-Einstein condensates: Variational solutions of the Gross-Pitaevskii equations

- V. Pérez-García, H. Michinel, J. Cirac, M. Lewenstein, P. Zoller
- Physics
- 1 August 1997

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 the… Expand
