Bayesian Searches and Quantum Oscillators
G. Chapline, M. Otten
A new LLNL Strategic Initiative is focused on developing improved methods for Bayesian inference when the input data depends on hidden parameters. Part of this effort involves inve…
Optical Detection and Storage of Entanglement in Plasmonically Coupled Quantum Dot Qubits
M. Otten, S. K. Gray, G. V. Kolmakov
Recent proposals and advances in quantum simulations, quantum cryptography and quantum communications substantially rely on quantum entanglement formation. Contrary to the conventi…
Fast Semistochastic Heat-Bath Configuration Interaction
Junhao Li, Matt Otten, Adam A Holmes +2
This paper presents in detail our fast semistochastic heat-bath configuration interaction (SHCI) method for solving the many-body Schrodinger equation. We identify and eliminate co…
Recovering noise-free quantum observables
Matthew Otten, Stephen Gray
We introduce a technique for recovering noise-free observables in noisy quantum systems by combining the results of many slightly different experiments. Our approach is applicable…
Accounting for Errors in Quantum Algorithms via Individual Error Reduction
Matthew Otten, Stephen Gray
We discuss a surprisingly simple scheme for accounting (and removal) of error in observables determined from quantum algorithms. A correction to the value of the observable is calc…
Excited States of Methylene, Polyenes, and Ozone from Heat-Bath Configuration Interaction
Alan D. Chien, Adam A. Holmes, Matthew Otten +3
The electronically excited states of methylene (CH), ethylene (CH), butadiene (CH), hexatriene (CH), and ozone (O) have long proven challenging due…
