Albert Einstein once dubbed Quantum Entanglement "spooky actions at a distance," and the concept remains one of the starkest examples of how quantum theory differs from our usual intuitions about space, time, and matter. Physicists have tested quantum entanglement in laboratories for forty years, and have always found results consistent with quantum theory; today entanglement is at the heart of next-generation devices like quantum computers and quantum encryption. Yet every experimental test to date has been subject to one or more "loopholes," which could possibly account for the results even in the absence of genuine quantum entanglement. This lecture describes the latest experimental tests of quantum entanglement, including a new experiment that uses some of the oldest light in the universe to address the last major loophole and pave the way for a genuinely loophole-free test of quantum entanglement.



Sir David I. Kaiser, has been a Germeshausen Professor of the History of Science and Department Head of Program in Science, Technology & Society at the Massachusetts Institute of Technology. He has also been a Professor of Physics at MIT. His physics research is in particle cosmology, working at the interface of particle physics and gravitation. In particular, most of his work has focused on inflationary cosmology.
