ICTP-SISSA Colloquium by Prof. Subir Sachdev, Harvard, on "Quantum Entanglement at all Distances"

Joint ICTP-SISSA Colloquium by Prof. Subir Sachdev, Harvard University, USA, on "Quantum Entanglement at all Distances" Speaker: Prof. Subir Sachdev, Herchel Smith Professor of Physics at Harvard University, USA Abstract of the Colloquium: Entanglement is the strangest feature of quantum theory, often dubbed ''spooky action at a distance’’. Quantum entanglement can occur on a macroscopic scale with trillions of electrons, leading to novel superconductors which can conduct electricity without resistance even at relatively high temperatures. These superconductors also display a “strange metal” regime in which individual electrons lose their identity. Related entanglement structures arise across the horizon of a black hole, and give rise to Hawking’s quantum paradox. I will introduce and describe these long-standing problems in two very different fields of physics, and review progress in resolving them using insights from the Sachdev-Ye-Kitaev model.
