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…

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…
