Query: Information back-flow in quantum non-Markovian dynamics and its
  connection to teleportation   A quantum process is called non-Markovian when memory effects take place
during its evolution. Quantum non-Markovianity is a phenomenon typically
associated with the information back-flow from the environment to the principal
system, however it has been shown that such an effect is not necessary. In
particular, maximum quantum non-Markovianity can be achieved without any
physical transmission of information. In this work, it is shown that
time-homogeneity is a sufficient condition for a non-Markovian quantum process
to originate from an information back-flow effect. As a characteristic example,
the protocol of measurement-free teleportation is suggested as a
time-homogeneous maximally non-Markovian quantum process, in both discrete and
continuous-variable systems. Finally, given the resource-like role of
entanglement in teleportation protocol, the relationship between this property
and non-Markovianity is elucidated.
