“Time in Experiments on Quantum Entanglement (and Beyond)”
Come prepared to offer your guesses and predictions, as we describe several distinct kinds of time reversals that have arisen in discussions of experimental observations made in our labs, including issues that arise in interpreting “Ghost Imaging,” which uses quantum mechanically entangled photon pairs, where the photons incident upon the detecting camera have never interacted with the object imaged. For broader context, we discuss our recent work on Faster- Than-Light Imaging, which experimentally demonstrates creation and annihilation of spot pair images (where one spot moves forward in time and another moves backwards in time).
