Description
In the 1930s, Erwin Schrödinger recognized quantum entanglement not only as an interesting and counter-intuitive feature of multiparticle quantum states, but also as the aspect of quantum mechanics that distinguishes it most strongly from classical physics. In today’s “second quantum revolution,” entanglement plays key roles in quantum computing, quantum information science, and enhanced quantum sensing. This talk addresses the question of how to introduce students most effectively to entangled states and their significance. I argue that an effective approach emphasizes the correlations between measurements on the separated parts of the entangled state. By focusing on the probabilities of those measurement outcomes, which can be read directly from the formal state vector for the composite entangled state, we can avoid inducing common misconceptions while demonstrating the critical quantum nonlocality expressed by those correlations.
