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…
Detecting Entanglement can be More Effective with Inequivalent Mutually Unbiased Bases
B. C. Hiesmayr, D. McNulty, S. Baek +3
Mutually unbiased bases (MUBs) provide a standard tool in the verification of quantum states, especially when harnessing a complete set for optimal quantum state tomography. In thi…
Quantum evolution with a large number of negative decoherence rates
Katarzyna Siudzińska, Dariusz Chruściński
Non-Markovian effects in quantum evolution appear when the system is strongly coupled to the environment and interacts with it for long periods of time. To include memory effects i…
Construction of propagators for divisible dynamical maps
Ujan Chakraborty, Dariusz Chruściński
Divisible dynamical maps play an important role in characterizing Markovianity on the level of quantum evolution. Divisible maps provide important generalization of Markovian semig…
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 (…
