Classical systems cannot simulate quantum systems efficiently (widely believed but unproven)

??? Quantum Supremacy!

(Maybe. We don’t actually know for sure.) particle collision molecular chemistry entangled electrons A quantum computer can simulate efficiently any physical process that occurs in Nature. (Maybe. We don’t actually know for sure.) superconductor black hole early universe
