Talk Title:  “Quantum computation for chemistry and materials”


Quantum computers promise to dramatically advance our understanding of new materials and novel chemistry. Recent advances in the technologies related to quantum computing hardware suggest that devices capable of so-called "quantum supremacy" may be available in the next few years.  In this talk I will focus on the application of quantum computers to hard problems in the application area of chemistry and materials, and discuss the challenges and opportunities related to current algorithms. I will begin with an introduction to quantum computation appropriate for individuals with broad backgrounds in physics.  I will then describe one particular method of interest to overcome quantum resource requirements, the variational quantum eigensolver (VQE).  This hybrid quantum-classical method provides a way of solving eigenvalue problems and more generic optimizations on a quantum device leveraging classical resources to minimize coherence time requirements.  I will briefly review the original VQE approach and introduce some extensions requiring no additional coherence time to approximate excited states.  I will close with an outlook on the prospects for near-term experiments and time permitting some connections to quantum neural networks.
