Optimizing and Comparing Quantum Resources of Statistical Phase Estimation and Krylov Subspace Diagonalization
Oumarou Oumarou, Pauline J. Ollitrault, Stefano Polla +1
We develop a framework that enables direct and meaningful comparison of two early fault-tolerant methods for the computation of eigenenergies, namely \gls{qksd} and \gls{spe}, with…
Molecular Properties from Quantum Krylov Subspace Diagonalization
Oumarou Oumarou, Pauline J. Ollitrault, Cristian L. Cortes +3
Quantum Krylov subspace diagonalization is a prominent candidate for early fault tolerant quantum simulation of many-body and molecular systems, but so far the focus has been mainl…
Error mitigation and circuit division for early fault-tolerant quantum phase estimation
Alicja Dutkiewicz, Stefano Polla, Maximilian Scheurer +3
As fully fault-tolerant quantum computers capable of solving useful problems remain a distant goal, we anticipate an era of "early fault tolerance" where limited error correction i…
Simulating Chemistry with Fermionic Optical Superlattices
Fotios Gkritsis, Daniel Dux, Jin Zhang +3
We show that quantum number preserving Ansätze for variational optimization in quantum chemistry find an elegant mapping to ultracold fermions in optical superlattices. Using nativ…
Tailored and Externally Corrected Coupled Cluster with Quantum Inputs
Maximilian Scheurer, Gian-Luca R. Anselmetti, Oumarou Oumarou +2
We propose to use wavefunction overlaps obtained from a quantum computer as inputs for the classical split-amplitude techniques, tailored and externally corrected coupled cluster,…
Estimation of electrostatic interaction energies on a trapped-ion quantum computer
Pauline J. Ollitrault, Matthias Loipersberger, Robert M. Parrish +12
We present the first hardware implementation of electrostatic interaction energies using a trapped-ion quantum computer. As test system for our computation, we focus on the reducti…
Quantum Simulation of Realistic Materials in First Quantization Using Non-local Pseudopotentials
Dominic W. Berry, Nicholas C. Rubin, Ahmed O. Elnabawy +5
This paper improves and demonstrates the usefulness of the first quantized plane-wave algorithms for the quantum simulation of electronic structure, developed by Babbush et al. and…
