Journal ArticleDOI
Fast semistochastic heat-bath configuration interaction
TL;DR: In this article, a fast semistochastic heat-bath configuration interaction (SHCI) method for solving the many-body Schrodinger equation is presented, which identifies and eliminates computational bottlenecks in both the variational and perturbative steps.
Journal ArticleDOI
Excited States of Methylene, Polyenes, and Ozone from Heat-Bath Configuration Interaction.
Alan D. Chien,Adam A. Holmes,Adam A. Holmes,Matthew Otten,Cyrus Umrigar,Sandeep Sharma,Paul M. Zimmerman +6 more
TL;DR: These calculations strongly support the presence of a previously hypothesized ring-minimum species of ozone that lies 1.3 eV higher than the open-ring-minimum energy structure and is separated from it by a barrier of 1.11 eV.
Journal ArticleDOI
Recovering noise-free quantum observables
Matthew Otten,Stephen K. Gray +1 more
TL;DR: In this article, a technique for recovering noise-free observables in noisy quantum systems by combining the results of many slightly different experiments is introduced, which corresponds to repeating the same quantum evolution many times with known variations on the underlying systems' error properties.
Journal ArticleDOI
Entanglement of two, three, or four plasmonically coupled quantum dots
Matthew Otten,Matthew Otten,Raman A. Shah,Norbert F. Scherer,Misun Min,Matthew Pelton,Stephen Gray +6 more
TL;DR: In this paper, the quantum dynamics of two, three, or four quantum dots (QDs) in proximity to a plasmonic system such as a metal nanoparticle or an array of metal nanoparticles are modeled.
Journal ArticleDOI
Cooling a mechanical resonator with nitrogen-vacancy centres using a room temperature excited state spin-strain interaction.
TL;DR: A protocol to dissipatively cool a room temperature mechanical resonator using a nitrogen-vacancy centre ensemble and the spin ensemble is coupled to the resonator through its orbitally-averaged excited state, which has a spin–strain interaction that has not been previously studied.
