Web1 day ago · The man responsible for the leak of hundreds of classified Pentagon documents is reported to be a young, racist gun enthusiast who worked on a military base, and who … The basic Fredkin gate is a controlled swap gate that maps three inputs (C, I1, I2) onto three outputs (C, O1, O2). The C input is mapped directly to the C output. If C = 0, no swap is performed; I1 maps to O1, and I2 maps to O2. Otherwise, the two outputs are swapped so that I1 maps to O2, and I2 maps to O1. It is easy to see that this circuit is reversible, i.e., "undoes" itself when run backwards. A generalized n×n Fredkin gate passes its first n−2 inputs unchanged to the corresp…
