Quantum Entanglement in Nature - High Temperature Superconductors and Black Holes

Explore a fascinating physics colloquium lecture by Harvard University's Subir Sachdev examining the mysterious phenomenon of quantum entanglement and its manifestation in both high-temperature superconductors and black holes. Delve into Einstein's "spooky action at a distance" and discover how quantum entanglement operates on a massive scale, involving millions of electrons to create strange metals and novel superconductors capable of conducting electricity without resistance at relatively high temperatures. Learn about the surprising connections between particle entanglement and black hole horizons, including their relationship to Hawking's black hole entropy. Examine simple models of many-particle quantum entanglement that provide insights into persistent questions across these seemingly disparate physical systems.
