Stochastic Tensor Contraction for Efficient MP2 Exchange
Jiace Sun, Garnet Kin-Lic Chan
Second-order Moller--Plesset perturbation theory (MP2) is one of the simplest correlated wave-function methods, but its conventional cost limits its application to large s…

Shadow tomography for classical tensor network simulations
Jiace Sun, Garnet Kin-Lic Chan
Shadow tomography has appeared as a powerful tool for estimating observables on quantum computers from a small number of samples. We show that shadow-tomography-inspired ideas can…

Stochastic tensor contraction for quantum chemistry
Jiace Sun, Garnet Kin-Lic Chan
Many computational methods in ab initio quantum chemistry are formulated in terms of high-order tensor contractions, whose cost determines the size of system that can be studied. W…
