Quantum-Centric Geometry Optimization with Wave-Function-Based Embedding
Danil Kaliakin, Akhil Shajan, Fangchun Liang +2
The EWF-(FCI,SQD) method, a wave-function-based embedding approach combining full configuration interaction (FCI) and sample-based quantum diagonalization (SQD), is a promising new…
Quantum Computing Enabled ab initio Molecular Dynamics Simulations
Susanta Das, Subhamoy Bhowmik, Zhen Li +4
We demonstrate a quantum-classical workflow for ab initio molecular dynamics (AIMD) in which quantum measurements from a chemistry-inspired LUCJ ansatz are post-processed using Sam…
Quantum Computations on Fusion Blanket Molten Salts
Susanta Das, Thiago J. Pinheiro Dos Santos, Subhamoy Bhowmik +14
Molten salts such as FLiBe (2LiF--BeF) are leading blanket materials for breeding and recovering tritium in fusion reactors. Predicting tritium speciation requires accurate ele…
Crossing the 12,000-atom barrier with heterogeneous quantum-classical supercomputing: quantum chemistry of protein-ligand complexes
Kenneth M. Merz, Akhil Shajan, Danil Kaliakin +21
We develop a workflow decomposing a molecule into fragments via quantum embedding and simulating them with a heterogeneous quantum-classical (HQC) method. We sample fragment electr…
Protein-Ligand Free Energy Perturbation on Quantum Hardware
Zhen Li, Milana Bazayeva, Thaddeus Pellegrini +6
The use of free energy perturbation (FEP) methods to study protein-ligand complexes is one of the most important tools in structure-based drug design. Because FEP methods typically…
Molecular Quantum Computations on a Protein
Akhil Shajan, Danil Kaliakin, Fangchun Liang +7
This work presents the implementation of a fragment-based, quantum-centric supercomputing workflow for computing molecular electronic structure using quantum hardware. The workflow…
Quantum-Centric Alchemical Free Energy Calculations
Milana Bazayeva, Zhen Li, Danil Kaliakin +4
In the present work, we present a hybrid quantum-classical workflow aimed at improving the accuracy of alchemical free energy (AFE) predictions by incorporating configuration inter…
Implicit solvent sample-based quantum diagonalization
Danil Kaliakin, Akhil Shajan, Fangchun Liang +1
The sample-based quantum diagonalization (SQD) method shows great promise in quantum-centric simulations of ground state energies in molecular systems. Inclusion of solute-solvent…
Towards quantum-centric simulations of extended molecules: sample-based quantum diagonalization enhanced with density matrix embedding theory
Akhil Shajan, Danil Kaliakin, Abhishek Mitra +9
Computing ground-state properties of molecules is a promising application for quantum computers operating in concert with classical high-performance computing resources. Quantum em…
Accurate quantum-centric simulations of supramolecular interactions
Danil Kaliakin, Akhil Shajan, Javier Robledo Moreno +9
We present the first quantum-centric simulations of noncovalent interactions using a supramolecular approach. We simulate the potential energy surfaces (PES) of the water and metha…
