An invitation to Quantum Game Theory
E. W. Piotrowski, J. Sladkowski
Recent development in quantum computation and quantum information theory allows to extend the scope of game theory for the quantum world. The paper presents the history, basic idea…
Correlations and entanglement in probability theory
E. G. Beltrametti, S. Bugajski
We generalize the classical probability frame by adopting a wider family of random variables that includes nondeterministic ones. The frame that emerges is known to host a ''classi…
The generalized partial transposition criterion for separability of multipartite quantum states
Kai Chen, Ling-An Wu
We present a generalized partial transposition separability criterion for the density matrix of a multipartite quantum system. This criterion comprises as special cases the famous…
Damped Bloch oscillations of cold atoms in optical lattices
A. R. Kolovsky, A. V. Ponomarev, H. J. Korsch
The paper studies Bloch oscillations of cold neutral atoms in the optical lattice. The effect of spontaneous emission on the dynamics of the system is analyzed both analytically an…
Relativistic coherent states and charge structure of the coordinate and momentum operators
B. I. Lev, A. A. Semenov, C. V. Usenko +1
We consider relativistic coherent states for a spin-0 charged particle that satisfy the next additional requirements: (i) the expected values of the standard coordinate and momentu…
A matrix realignment method for recognizing entanglement
Kai Chen, Ling-An Wu
Motivated by the Kronecker product approximation technique, we have developed a very simple method to assess the inseparability of bipartite quantum systems, which is based on a re…
