The Quest to Build a Quantum Computer

These amazing possibilities that you're describing of these quantum many body systems that somehow manage to stay far from equilibrium, I don't know that I've ever seen one in my house. Is this something that occurs in the natural world? No, no, so unlike diamond or rock salt, you know, you can't go mining for time crystals. So these are phenomena that exist in highly engineered quantum systems. And indeed, a lot of this effort has been motivated by the quest to build a quantum computer. We're very, very far from there now.
