Counterfactual Quantum Computation is Really Weird

Events that could have happened but didn’t, so called counterfactual events, are but a mind-game in our reality. In quantum reality, however, they are quite real indeed. In this video I explain how this can be used to do a computation without actually running the computer. This is called “counterfactual computation” (or “counterfactual quantum computation” more specifically).
