Quantum-centric simulation of hydrogen abstraction by sample-based quantum diagonalization and entanglement forging
Tyler Smith, Tanvi P. Gujarati, Mario Motta +11
The simulation of electronic systems is an anticipated application for quantum-centric computers, i.e. heterogeneous architectures where classical and quantum processing units oper…
Symmetry-based perturbation theory for electronic structure calculations
Hiromichi Nishimura, Nam Nguyen, Tanvi Gujarati +1
We develop a multi-reference perturbation theory for electronic structure calculations based on symmetries of the Hamiltonian. The reference Hamiltonian in the symmetry-based pertu…
Sample-based quantum diagonalization as parallel fragment solver for the localized active space self-consistent field method
Qiaohong Wang, Mario Motta, Ruhee D'Cunha +7
Accurately and efficiently describing strongly correlated electronic systems is a central challenge in quantum computational chemistry, with classical and quantum computers. The lo…
Adiabatic state preparation from general initial states
Bryce Fuller, Mario Motta, Stuart M. Harwood +4
A variety of quantum computing algorithms exist for the preparation of approximate Hamiltonian ground states. A natural and important question is how these ground-state approximati…
Scaling active spaces in simulations of surface reactions through sample-based quantum diagonalization
Marco Antonio Barroca, Tanvi Gujarati, Vidushi Sharma +6
Quantum-chemical simulations are essential for predicting energies of chemical reactions. Accurately solving the many-body Schrödinger equation for reagent and product states of m…
Sample-based Quantum Diagonalization Methods for Modeling the Photochemistry of Diazirine and Diazo Compounds
Saurabh Shivpuje, Tanvi P. Gujarati, Richard Van +6
Diazirines and diazo compounds are widely employed as photoreactive precursors for generating carbenes, key intermediates in chemical biology and materials science. However, comput…
