Interaction free and decoherence free states
Dariusz Chruściński, Anna Napoli, Marina Guccione +2
An interaction free evolving state of a closed bipartite system composed of two interacting subsystems is a generally mixed state evolving as if the interaction were a c-number. In…
Interaction-free evolution in the presence of time-dependent Hamiltonians
Dariusz Chruściński, Antonino Messina, Benedetto Militello +1
The generalization of the concept of interaction-free evolutions (IFE) [A. Napoli, {\it et al.}, Phys. Rev. A {\bf 89}, 062104 (2014)] to the case of time-dependent Hamiltonians is…
Decoherence-free subspaces for a quantum register interacting with a spin environment
Paweł Należyty, Dariusz Chruściński
We study a model of a quantum spin register interacting with an environment of spin particles in quantum-measurement limit. In the limit of collective decoherence we obtain the for…
Indecomposable optimal entanglement witnesses in C4 {\otimes} C4
Dariusz Chruściński, Filip A. Wudarski
We provide two 1-parameter families of indecomposable entanglement witnesses in C4 {\otimes} C4. Following recent paper by Ha and Kye [Phys. Rev. A 84, 024302 (2011)] we show that…
General form of quantum evolution
Dariusz Chruscinski, Andrzej Kossakowski
We propose a complete treatment of a local in time dynamics of open quantum systems. In this approach Markovian evolution turns out to be a special case of a general non-Markovian…
A class of Bell diagonal states and entanglement witnesses
D. Chruscinski, A. Kossakowski, K. Mlodawski +1
We analyze special class of bipartite states - so called Bell diagonal states. In particular we provide new examples of bound entangled Bell diagonal states and construct the class…
