Amplified Amplitude Estimation: Exploiting Prior Knowledge to Improve Estimates of Expectation Values
Sophia Simon, Matthias Degroote, Nikolaj Moll +3
We provide a method for estimating the expectation value of an operator that can utilize prior knowledge to accelerate the learning process on a quantum computer. Specifically, sup…
Fault-tolerant quantum algorithm for symmetry-adapted perturbation theory
Cristian L. Cortes, Matthias Loipersberger, Robert M. Parrish +9
The efficient computation of observables beyond the total energy is a key challenge and opportunity for fault-tolerant quantum computing approaches in quantum chemistry. Here we co…
Quantum-enhanced quantum Monte Carlo: an industrial view
Maximilian Amsler, Peter Deglmann, Matthias Degroote +10
In this work, we test a recently developed method to enhance classical auxiliary-field quantum Monte Carlo (AFQMC) calculations with quantum computers against examples from chemist…
Interaction Energies on Noisy Intermediate-Scale Quantum Computers
Matthias Loipersberger, Fionn D. Malone, Alicia R. Welden +7
The computation of interaction energies on noisy intermediate-scale quantum (NISQ) computers appears to be challenging with straightforward application of existing quantum algorith…
Measuring correlations of cold atom systems using multiple quantum probes
Michael Streif, Andreas Buchleitner, Dieter Jaksch +1
We present a non-destructive method to probe a complex quantum system using multiple impurity atoms as quantum probes. Our protocol provides access to different equilibrium propert…
