Quantum Machine Learning using Gaussian Processes with Performant Quantum Kernels

Matthew Otten, Imène R. Goumiri, Benjamin W. Priest +2

Quantum computers have the opportunity to be transformative for a variety of computational tasks. Recently, there have been proposals to use the unsimulatably of large quantum devi…

Accurate and efficient description of interacting carriers in quantum nanostructures by selected configuration interaction and perturbation theory

Moritz Cygorek, Matthew Otten, Marek Korkusinski +1

We present a method to calculate many-body states of interacting carriers in million atom quantum nanostructures based on atomistic tight-binding calculations and a combination of…

Ground-state cooling enabled by critical coupling and dark entangled states

Cristian L. Cortes, Matthew Otten, Stephen K. Gray

We analyze the cooling of a mechanical resonator coupled to an ensemble of interacting two-level systems via an open quantum systems approach. Using an exact analytical result, we…

Non-Hermitian approach for quantum plasmonics

Cristian L. Cortes, Matthew Otten, Stephen K. Gray

We examine the limits of applicability of a simple non-Hermitian model for exciton/plasmon interactions in the presence of dissipation and dephasing. The model can be used as an al…

Noise-Resilient Quantum Dynamics Using Symmetry-Preserving Ansatzes

Matthew Otten, Cristian L. Cortes, Stephen K. Gray

We describe and demonstrate a method for the computation of quantum dynamics on small, noisy universal quantum computers. This method relies on the idea of `restarting' the dynamic…

Accurate many-body electronic structure near the basis set limit: application to the chromium dimer

Junhao Li, Yuan Yao, Adam A. Holmes +4

We describe a method for computing near-exact energies for correlated systems with large Hilbert spaces. The method efficiently identifies the most important basis states (Slater d…
