Chemistry and Quantum Mechanics [PDF]

open access: yesJournal of the Chinese Chemical Society, 2021
Of quantum physics, quantum chemistry and quantum mechanics, the latter is least useful for both chemical education and the practice of chemistry as a science concerned with the reactions and properties of chemical substances. We show that quantum mechanics must be viewed as a collection of methods, numbering at least thirteen, that one might ...

Electrocatalysis with quantum chemistry [PDF]

open access: yesEPJ Web of Conferences, 2022
The following article presents a brief introduction to modeling an electrochemical reaction. Two crucial concepts, oxidation-reduction and acid-base reactions, are briefly illustrated to understand the structural changes of the electro-catalyst.

Towards practical and massively parallel quantum computing emulation for quantum chemistry

open access: yesnpj Quantum Information, 2023
Quantum computing is moving beyond its early stage and seeking for commercial applications in chemical and biomedical sciences. In the current noisy intermediate-scale quantum computing era, the quantum resource is too scarce to support these ...

Improving quantum algorithms for quantum chemistry [PDF]

open access: yesQuantum Information and Computation, 2015
We present several improvements to the standard Trotter-Suzuki based algorithms used in the simulation of quantum chemistry on a quantum computer. First, we modify how Jordan-Wigner transformations are implemented to reduce their cost from linear or logarithmic in the number of orbitals to a constant.

Topological quantum chemistry [PDF]

open access: yesNature, 2017
The past decade's apparent success in predicting and experimentally discovering distinct classes of topological insulators (TIs) and semimetals masks a fundamental shortcoming: out of 200,000 stoichiometric compounds extant in material databases, only several hundred of them are topologically nontrivial.

Massively Scalable Workflows for Quantum Chemistry: BIGCHEM and CHEMCLOUD [PDF]

open access: yes, 2023
Electronic structure theory, i.e. quantum chemistry, is the fundamental building block for many problems in computational chemistry. We present a new distributed computing framework (BIGCHEM) which allows efficient solution of many quantum chemistry ...
