Efficient quantum circuits for diagonal unitaries without ancillas
(IOP Publishing, 2014)
The accurate evaluation of diagonal unitary operators is often the most resource-intensive element of quantum algorithms such as real-space quantum simulation and Grover search. Efficient circuits have been demonstrated ...
Quantum information for chemistry and biology
(American Physical Society, 2009)
La biología cuántica ¿un nuevo campo de la química?
(Universidad Nacional Autónoma de México, 2011)
Over the past century quantum mechanics has been widely applied in the understanding of several physical phenomena. In chemistry, particularly, quantum mechanics have been fundamental for confirmation of chemical insights, ...
Theoretical characterization of excitation energy transfer in chlorosome light-harvesting antennae from green sulfur bacteria
(Springer Science + Business Media, 2014)
We present a theoretical study of excitation dynamics in the chlorosome antenna complex of green photosynthetic bacteria based on a recently proposed model for the molecular assembly. Our model for the excitation energy ...
More Accurate and Efficient Bath Spectral Densities from Super-Resolution
(2013)
Quantum transport and other phenomena are typically modeled by coupling the system of interest to an environment, or bath, held at thermal equilibrium. Realistic bath models are at least as challenging to construct as ...
Photonics meets excitonics: natural and artificial molecular aggregates
(Walter de Gruyter GmbH, 2013)
Organic molecules store the energy of absorbed light in the form of charge-neutral molecular excitations -- Frenkel excitons. Usually, in amorphous organic materials, excitons are viewed as quasiparticles, localized on ...
Effects of Odd–Even Side Chain Length of Alkyl-Substituted Diphenylbithiophenes on First Monolayer Thin Film Packing Structure
(American Chemical Society, 2013)
Because of their preferential two-dimensional layer-by-layer growth in thin films, 5,5′bis(4-alkylphenyl)-2,2′-bithiophenes (P2TPs) are model compounds for studying the effects of systematic chemical structure variations ...
Confined Organization of Fullerene Units Along High Polymer Chains
(Royal Society of Chemistry (RSC), 2013)
Conductive fullerene \((C_{60})\) units were designed to be arranged in one dimensional close contact by locally organizing them with covalent bonds in a spatially constrained manner. Combined molecular dynamics and quantum ...
Quantum process tomography of excitonic dimers from two-dimensional electronic spectroscopy. I. General theory and application to homodimers
(AIP Publishing, 2011)
Is it possible to infer the time evolving quantum state of a multichromophoric system from a sequence of two-dimensional electronic spectra (2D-ES) as a function of waiting time? Here we provide a positive answer for a ...
From Transistor to Trapped-ion Computers for Quantum Chemistry
(Nature Publishing Group, 2014)
Over the last few decades, quantum chemistry has progressed through the development of computational methods based on modern digital computers. However, these methods can hardly fulfill the exponentially-growing resource ...
