Even More Efficient Quantum Computations of Chemistry Through Tensor Hypercontraction
We describe quantum circuits with only O[over ~](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...
