Abstract

Quantum computers use the principles of quantum mechanics to perform computation in a way fundamentally different from traditional ("classical") algorithms. This new computational paradigm shows great promise in revolutionizing our ability to understand and solve complex problems in physics, optimization, and learning. However, establishing the precise conditions under which quantum algorithms outperform classical ones is a surprisingly nuanced question. In this talk, I will show how the complexity of typical instances of problems can be understood using ideas from statistical physics, and through this new perspective present a framework for understanding the relative performance of quantum versus classical algorithms in optimization and simulation.
