Even More Efficient Quantum Computations of Chemistry Through Tensor Hypercontraction

We describe quantum circuits with only O ~ ( N ) Toffoli complexity that block encode the spectra of quantum chemistry Hamiltonians in a basis of N arbitrary (e.g., molecular) orbitals. With O ( λ/ϵ ) repetitions of these circuits one can use phase estimation to sample in the molecular eigenbasis, w...
