Sufficient separability criteria and linear maps
Maciej Lewenstein, Remigiusz Augusiak, Dariusz Chruściński +2
We study families of positive and completely positive maps acting on a bipartite system (with ). The maps have a property that when appl…
Trace-distance measure of coherence
Swapan Rana, Preeti Parashar, Maciej Lewenstein
We show that trace distance measure of coherence is a strong monotone for all qubit and, so called, states. An expression for the trace distance coherence for all pure states a…
Towards resource theory of coherence in distributed scenarios
Alexander Streltsov, Swapan Rana, Manabendra Nath Bera +1
The search for a simple description of fundamental physical processes is an important part of quantum theory. One example for such an abstraction can be found in the distance lab p…
Assisted distillation of quantum coherence
E. Chitambar, A. Streltsov, S. Rana +3
We introduce and study the task of assisted coherence distillation. This task arises naturally in bipartite systems where both parties work together to generate the maximal possibl…
Asymptotic role of entanglement in quantum metrology
Remigiusz Augusiak, Jan Kolodynski, Alexander Streltsov +3
Quantum systems allow one to sense physical parameters beyond the reach of classical statistics---with resolutions greater than , where is the number of constituent partic…
Nonlocality in many-body quantum systems detected with two-body correlators
J. Tura, R. Augusiak, A. B. Sainz +4
Contemporary understanding of correlations in quantum many-body systems and in quantum phase transitions is based to a large extent on the recent intensive studies of entanglement…
Entanglement and Nonlocality in Many-Body Systems: a primer
J. Tura, A. B. Sainz, T. Grass +3
Current understanding of correlations and quantum phase transitions in many-body systems has significantly improved thanks to the recent intensive studies of their entanglement pro…
