Detection power of separability criteria based on a correlation tensor: a case study
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński
Detection power of separability criteria based on a correlation tensor is tested within a family of generalized isotropic state in . For all these c…
Eternally non-Markovian dynamics of a qubit interacting with a single-photon wavepacket
Anita Dąbrowska, Dariusz Chruściński, Sagnik Chakraborty +1
An evolution of a two-level system (qubit) interacting with a single-photon wave packet is analyzed. It is shown that a hierarchy of master equations gives rise to phase covariant…
Topologically protected gap states and resonances in gated trilayer graphene
W. Jaskólski, G. Sarbicki
Gated trilayer graphene exhibits energy gap in its most stable ABC stacking. Here we show that when the stacking order changes from ABC to CBA, three gapless states appear in each…
On the Alberti-Uhlmann Condition for Unital Channels
Sagnik Chakraborty, Dariusz Chruściński, Gniewomir Sarbicki +1
We address the problem of existence of completely positive trace preserving (CPTP) maps between two sets of density matrices. We refine the result of Alberti and Uhlmann and derive…
Enhanced realignment criterion vs. linear entanglement witnesses
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński
It is shown that the enhanced (nonlinear) realignment criterion is equivalent to the family of linear criteria based on correlation tensor. These criteria generalize the original (…
A family of multipartite separability criteria based on correlation tensor
Gniewomir Sarbicki, Giovanni Scala, Dariusz Chruściński
A family of separability criteria based on correlation matrix (tensor) is provided. Interestingly, it unifies several criteria known before like e.g. CCNR or realignment criterion,…
