Generalizing Choi map in beyond circulant scenario
Anindita Bera, Giovanni Scala, Gniewomir Sarbicki +1
We present a generalization of the family of linear positive maps in proposed thirty years ago by Cho et al. (Linear Algebra Appl. , 213 (1992)) as a generalizatio…
Time inhomogeneous quantum dynamical maps
Dariusz Chruściński
We discuss a wide class of time inhomogeneous quantum evolution which is represented by two-parameter family of completely positive trace-preserving maps. These dynamical maps are…
Dynamical maps beyond Markovian regime
Dariusz Chruściński
Quantum dynamical maps provide suitable mathematical representation of quantum evolutions. It is the very notion of complete positivity which provides a proper mathematical represe…
Bounding the Frobenius norm of a q-deformed commutator
Dariusz Chruściński, Gen Kimura, Hiromichi Ohno +1
For two complex matrices and , we define the -deformed commutator as for a real parameter . In this paper, we investigate a gen…
Quantum regression in dephasing phenomena
Davide Lonigro, Dariusz Chruściński
We investigate the validity of quantum regression for a family of quantum Hamiltonians on a multipartite system leading to phase-damping reduced dynamics. After finding necessary a…
