Real-space density functional theory on graphical processing units: computational approach and comparison to Gaussian basis set methods
Xavier Andrade,Alán Aspuru-Guzik +1 more
TL;DR: Results for current-generation GPUs from AMD and Nvidia show that the implementation, implemented in the free code Octopus, can reach a sustained performance of up to 90 GFlops for a single GPU, representing a significant speed-up when compared to the CPU version of the code.
Atomistic study of energy funneling in the light-harvesting complex of green sulfur bacteria
Joonsuk Huh,Semion K. Saikin,Jennifer C. Brookes,Jennifer C. Brookes,Stéphanie Valleau,Takatoshi Fujita,Alán Aspuru-Guzik +6 more
TL;DR: In this paper, an atomistic model that mimics a complete light-harvesting apparatus of green sulfur bacteria is presented. But the model is limited to the chlorosome, a baseplate and six Fenna-Matthews-Olson trimer complexes.

Single-Atom Heat Machines Enabled by Energy Quantization.
David Gelbwaser-Klimovsky,Alexei Bylinskii,Dorian Gangloff,Dorian Gangloff,Rajibul Islam,Alán Aspuru-Guzik,Vladan Vuletic +6 more
TL;DR: It is shown that energy quantization alone may alter and increase machine performance in terms of output work, efficiency, and even operation mode, and that quantum thermodynamics enables the realization of classically inconceivable Otto machines, such as those with an incompressible working substance.

Introduction to Quantum Algorithms for Physics and Chemistry
Man-Hong Yung,Man-Hong Yung,James D. Whitfield,James D. Whitfield,James D. Whitfield,Sergio Boixo,Sergio Boixo,David G. Tempel,Alán Aspuru-Guzik +8 more
TL;DR: In this paper, the authors focus on applications of quantum computation to chemical physics problems and describe the algorithms that have been proposed for the electronic- structure problem, the simulation of chemical dynamics, thermal state preparation, density functional theory and adiabatic quantum simulation.
Exponentially More Precise Quantum Simulation of Fermions in the Configuration Interaction Representation
Ryan Babbush,Ryan Babbush,Dominic W. Berry,Yuval R. Sanders,Ian D. Kivlichan,Artur Scherer,Annie Y. Wei,Peter J. Love,Alán Aspuru-Guzik +8 more
TL;DR: In this article, the authors present a quantum algorithm for the simulation of molecular systems that is asymptotically more efficient than all previous algorithms in the literature in terms of the main problem parameters.
