Completely Positive Divisibility Does Not Mean Markovianity

Author(s): Simon Milz, M. S. Kim, Felix A. Pollock, and Kavan Modi
In the classical domain, it is well known that divisibility does not imply that a stochastic process is Markovian. However, for quantum processes, divisibility is often considered to be synonymous with Markovianity. We show that completely positive divisible quantum processes can still involve non-M...
