There is also the interesting class of TSQT. Quantum theory is time symmetric as long as it can be described by the evolution of a state vector according to the Schroedinger equation. But as soon as measurement and wave function collapse are involved, the symmetry breaks down. But in the Time Symmetrized Quantum Theory (TSQT) it is argued that information propagating in a time reversed direction from future measurements can provide information about appropriately selected systems (!!!). Ensembles of such sustems are referred to as "pre-selected" and "post-selected". The basic claim of TSQT is that a fundamental time symmetry applies to the interval between two ideal measurements. According to TSQT the quantum state of a system, between two measurements occurring at times t1 and t2, contains information based not only on the initial measurement (pre-selection) but also on the final measurement (post-selection). Aharonov, Bergman and Lebowitz (ABL) invented the well-known time symmetric formalism for describing quantum systems between two complete measurements. Does TSQT ensures or forbids your win?
