A direct numerical algorithm for solving the time-nonlocal non-Markovian master equation in the second Born approximation is introduced and the range of utility of this approximation, and of the Marko...
Markovian and non-Markovian dynamics in quantum and classical systems
Markovian non-Markovian dynamics quantum classical systems

2010/11/8
We address continuous variable quantum key distribution (QKD) in non-Markovian lossy channels and show how the non-Markovian features may be exploited to enhance security and/or to detect the presence...

The non-Markovian dynamics of a qutrit system coupled to a bosonic environment is a difficult
problem due to the lack of an exact master equation. We present for the first time an exact
non-Markovia...
