    "abstract": "The observed probabilities of quantum mechanics possess a time asymmetry\nwhich is based on the truism that a state must be prepared before an observable\ncan be measured in it. While Hilbert space quantum theory cannot incorporate\nthis arrow of time, the Rigged Hilbert Space (RHS) formulation of quantum\nmechanics provides a theory of time symmetric as well as time asymmetric\nquantum physics.",
