Speaker: Shelly Goldstein, Rutgres mathematics department Title: What is Quantum Theory? Quantum theory is the basis of almost all of fundamental physics---and not just of quantum computing. Nonetheless it is not at all clear what quantum theory, regarded as a physical theory, actually says. I will elaborate here upon this rather odd claim. I will also describe an alternative to orthodox quantum mechanics, one that is, among all known formulations of quantum mechanics, the clearest, simplest, and least popular.
