Quantum Supremacy (video)

Scott Aaronson, David J. Bruton Centennial Professor of Computer Science, University of Texas at Austin

In the near future, there will likely be special-purpose quantum computers with 40-50 high-quality qubits. 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.
