Spectral amplification for ground-state energy estimation of electronic structure in first quantization
Alicja Dutkiewicz, Alec F. White, Guang Hao Low +6
We demonstrate an asymptotic gate complexity improvement in first-quantized ground-state energy estimation of electronic structure Hamiltonians in a plane wave basis by employing t…
A Denser Planar Surface Code
Guang Hao Low, William J. Huggins, Dominic W. Berry +4
We present a quantum code implementable on a regular D hex grid with an estimated encoding rate up to of that of a rotated surface code patch using circuit-level noi…
Fast quantum simulation of electronic structure by spectrum amplification
Guang Hao Low, Robbie King, Dominic W. Berry +6
The most advanced techniques using fault-tolerant quantum computers to estimate the ground-state energy of a chemical Hamiltonian involve compression of the Coulomb operator throug…
Rapid initial state preparation for the quantum simulation of strongly correlated molecules
Dominic W. Berry, Yu Tong, Tanuj Khattar +8
Studies on quantum algorithms for ground state energy estimation often assume perfect ground state preparation; however, in reality the initial state will have imperfect overlap wi…
