classical simulation of restricted quantum computations
... To postselect is to condition a probability space on the occurrence of a specific event. In other words, it is to dispose of all the runs of a computation in which a specific event does not occur. By employing postselection, the Boolean satisfiability problem can be solved efficiently – we give all ...
