    "abstract": "The basic concept of the two-state vector formalism, which is the time\nsymmetric approach to quantum mechanics, is the backward evolving quantum\nstate. However, due to the time asymmetry of the memory\u0027s arrow of time, the\npossible ways to manipulate a backward evolving quantum state differ from those\nfor a standard, forward evolving quantum state. The similarities and the\ndifferences between forward and backward evolving quantum states regarding the\nno-cloning theorem, nonlocal measurements, and teleportation are discussed. The\nresults are relevant not only in the framework of the two-state vector\nformalism, but also in the framework of retrodictive quantum theory.",
