Efficient ab initio auxiliary-field quantum Monte Carlo calculations in Gaussian bases via low-rank tensor decomposition
Mario Motta, James Shee, Shiwei Zhang +1
We describe an algorithm to reduce the cost of auxiliary-field quantum Monte Carlo (AFQMC) calculations for the electronic structure problem. The technique uses a nested low-rank f…

Low rank representations for quantum simulation of electronic structure
Mario Motta, Erika Ye, Jarrod R. McClean +4
The quantum simulation of quantum chemistry is a promising application of quantum computers. However, for N molecular orbitals, the gate complexity of performing…
