arXiv:quant-ph/9710036 · doi:10.1002/(SICI)1521-3978(199811)46:6/8<729::AID-PROP729>3.0.CO;2-Q
Abstract
A brief review of the time-symmetrized quantum formalism originated by Aharonov, Bergmann and Lebowitz is presented. Symmetry of various measurements under the time reversal is analyzed. Time-symmetrized counterfactuals are introduced. It is argued that the time-symmetrized formalism demonstrates novel profound features of quantum theory and that recent criticism of the formalism is unfounded.
