Complexity-Theoretic Foundations of Quantum Supremacy Experiments Scott Aaronson

Thursday, January 25, 2018 - 11:15 to 12:30 Auditorium

In the near future, there will likely be special-purpose quantum computers with 50 or so high-quality qubits and controllable nearest-neighbor couplings. In this talk, I'll discuss general theoretical foundations for how to use such devices to demonstrate "quantum supremacy": that is, a clear quantum speedup for *some* task, motivated by the goal of overturning the Extended Church-Turing Thesis (which says that all physical systems can be efficiently simulated by classical computers) as confidently as possible.
