Random generators of Markovian evolution: A quantum-classical transition by superdecoherence
W. Tarnowski, I. Yusipov, T. Laptyeva +3
Continuous-time Markovian evolution appears to be manifestly different in classical and quantum worlds. We consider ensembles of random generators of -dimensional Markovian evol…
Interpolating between positive and completely positive maps: a new hierarchy of entangled states
Katarzyna Siudzińska, Sagnik Chakraborty, Dariusz Chruściński
A new class of positive maps is introduced. It interpolates between positive and completely positive maps. It is shown that this class gives rise to a new characterization of entan…
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…
