What can quantum measurement tell us about the arrow of time? To answer this question, we use leading edge techniques involving superconducting circuits cooled to near absolute zero to capture “movies” of
quantum behavior. Press rewind on an ordinary movie of everyday life, and the movie looks strange and shows very unlikely behavior: people walk backwards, water flows up hill, and messy floors spontaneously become clean. It’s clear from watching an ordinary movie, which way is backwards and which is forwards, but is the same true for movies of quantum behavior? In this fascinating talk on our quantum world, physics professor, Kater Murch, shares these captured quantum movies and discusses how we can infer an arrow of time from quantum measurement alone.
