Episode notes

In principle, i could imagine taking a giant computer and solving for what the system is going to do using the shortenger equation. But in practice, that's just impractical. There's too many degrees of freedom, too many things going around. If the specific arrangements of entanglement and interactions a have this holographic duel, there's a way of thinking about them that looks like gravity in an extra dimension. It's not gravity in extra dimension, yetheres. We know ow dimensions are, et cetera. But you can use that knowledge to make a prediction for what's actually going to happen in your experiment, and then you can to see whether that comes true.

When it comes to thinking about quantum mechanics, there are levels. One level is shut-up-and-calculate: find a wave function, square it to get a probability. One level is foundational: dig deeply into the underlying ontology. But there’s a level in between, long neglected but recently coming to life. In this level you think about — or do experiments with — entangled quantum systems in the real world, putting entanglement to use. Monika Schleier-Smith is an experimental physicist specializing in cold atoms, which can be both entangled and manipulated. We discuss how to use such systems to study everything from metrology to quantum gravity.
