Arithmetic circuit tensor networks, multivariable function representation, and high-dimensional integration
Ruojing Peng, Johnnie Gray, Garnet Kin-Lic Chan
Many computational problems can be formulated in terms of high-dimensional functions. Simple representations of such functions and resulting computations with them typically suffer…
Is there evidence for exponential quantum advantage in quantum chemistry?
Seunghoon Lee, Joonho Lee, Huanchen Zhai +15
The idea to use quantum mechanical devices to simulate other quantum systems is commonly ascribed to Feynman. Since the original suggestion, concrete proposals have appeared for si…
Hyper-optimized approximate contraction of tensor networks with arbitrary geometry
Johnnie Gray, Garnet Kin-Lic Chan
Tensor network contraction is central to problems ranging from many-body physics to computer science. We describe how to approximate tensor network contraction through bond compres…
Using hyper-optimized tensor networks and first-principles electronic structure to simulate experimental properties of the giant {Mn84} torus
Dian-Teng Chen, Phillip Helms, Ashlyn R. Hale +7
The single-molecule magnet {Mn84} is a challenge to theory due to its high nuclearity. Building on our prior work which characterized the structure of the spectrum of this magnet,…
