Quasiparticle quantum simulation of materials with the Bethe-Salpeter equation
Jielun Chen, Jiace Sun, Garnet Kin-Lic Chan
The first-principles quantum simulation of the full electronic Hamiltonian of a material model of realistic size appears daunting even in a future era of fully fault-tolerant quant…
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…
Phase-sensitive representation of Majorana stabilizer states
Tomislav Begušić, Garnet Kin-Lic Chan
Stabilizer states hold a special place in quantum information science due to their connection with quantum error correction and quantum circuit simulation. In the context of classi…
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…
Ab Initio Many Body Quantum Embedding and Local Correlation in Crystalline Materials using Interpolative Separable Density Fitting
Junjie Yang, Ning Zhang, Shunyue Yuan +3
We present an efficient implementation of ab initio many-body quantum embedding and local correlation methods for infinite periodic systems through translational symmetry adapted i…
Systematic improvement of trial states in phaseless auxiliary-field quantum Monte Carlo
Eirik F. Kjønstad, Yann Damour, Sandeep Sharma +1
We extend the use of coupled cluster (CC) trial states in the phaseless auxiliary-field quantum Monte Carlo (AFQMC) method beyond single and double excitations to include both trip…
Convergence Analysis of the Stochastic Resolution of Identity: Comparing Hutchinson to Hutch++ for the Second-Order Green's Function
Leopoldo Mejía, Sandeep Sharma, Roi Baer +2
Stochastic orbital techniques offer reduced computational scaling and memory requirements to describe ground and excited states at the cost of introducing controlled statistical er…
