Quantum Mechanics of Time Travel

Seth Lloyd gave a talk on quantum computation with closed time like curves (CTCs), Nov. 4th 2010.  He begins in a light manner with examples of the many worlds vs consistent history perspectives and moves on to considering sending qubits through projective CTCs.  The talk ends with an experiment that is post-selectively equivalent to a projective CTC circuit.
