Exponentially faster antisymmetrization
Maria Kieferova
Modeling low energy eigenstates of fermionic systems can provide insight into chemical reactions and material properties, and is one of the most anticipated applications of quantum computing. I present a technique for reducing the cost of preparing fermionic Hamiltonian eigenstates. In particular, I will explain a polylogarithmic-depth quantum algorithm for antisymmetrizing the initial states required for simulation of fermions in first quantization. This is an exponential improvement over the previous state-of-the-art. Based on arXiv:1711.10460.
