Simulating chemistry efficiently on fault-tolerant quantum computers
N. Cody Jones,James D. Whitfield,Peter L. McMahon,Man-Hong Yung,Rodney Van Meter,Alán Aspuru-Guzik,Yoshihisa Yamamoto +6 more
TL;DR: In this paper, the authors consider methods to make proposed chemical simulation algorithms computationally fast on fault-tolerant quantum computers in the circuit model, and construct and analyze ecient implementations of rst and second-quantized simulation algorithms using the fault tolerant arbitrary gates and other techniques.

TL;DR: In this article, the authors show that low-order Trotter methods perform surprisingly well when used with phase estimation to compute relative precision quantities (e.g. energies per unit cell), as is often the goal for condensed-phase systems.
Theoretical Characterization of the Air-Stable, High-Mobility Dinaphtho[2,3-b:2′3′-f]thieno[3,2-b]-thiophene Organic Semiconductor
TL;DR: In this paper, the authors investigated the microscopic charge transport parameters of the DNTT molecule and crystal and showed that the moderate anisotropy of the hole mobility is highly dependent on the presence of in-plane herring-bonelike intermolecular interactions with large electronic coupling (transfer integral) values (ca. 0.1 eV).
Memory-assisted exciton diffusion in the chlorosome light-harvesting antenna of green sulfur bacteria
TL;DR: Despite the dynamical disorder effects on the electronic transitions of the bacteriochlorophylls, simulations show that the exciton delocalizes over the entire aggregate in about 200 fs, and exciton diffusion in the chlorosome is found to be highly anisotropic with the preferential transfer toward the baseplate, which is the next functional element in the photosynthetic system.
