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.
