• Abstract: 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 this work, we establish a connection between quantum non-Markovianity and the protocol of quantum teleportation in both discrete and continuous-variable systems. We also show how information flows during a teleportation protocol between the principal system and the environment in a bidirectional way leading up to a state revival.

• Reading a qubit quantum state with a quantum meter: time unfolding of quantum Darwinism and quantum information flux [0.0]
  Quantum non Markovianity and quantum Darwinism are two phenomena linked by a common theme: the flux of quantum information between a quantum system and the quantum environment it interacts with. We will show how, in some regimes, such quantum information flux is inefficient, leading to the simultaneous emergence of non Markovian and non darwinistic behaviours.
